The correct answer is Choice D.

Choice A rationale: Administering an oral corticosteroid is not the first action the nurse should take. Corticosteroids are used to reduce inflammation and itching caused by poison ivy. However, they are usually prescribed if the symptoms are severe or if the rash covers a large area of the body. It’s important to note that corticosteroids can have side effects, especially when used for a long time, so they should be used under the supervision of a healthcare provider.

Choice B rationale: Applying calamine lotion to the affected area can help soothe the skin and relieve itching caused by poison ivy. However, this is not the first action the nurse should take. The first step is to remove the oil from the skin that causes the allergic reaction. Calamine lotion can be applied after the area has been thoroughly washed.

Choice C rationale: Instructing the parent to give the child an oatmeal bath twice daily can help soothe the skin and relieve itching. However, this is not the first action the nurse should take. Similar to calamine lotion, an oatmeal bath can be beneficial after the area has been thoroughly washed to remove the oil from the skin.

Choice D rationale: The first action the nurse should take when caring for a child exposed to poison ivy is to flush the area with cold, running water. This helps to remove the oil (urushiol) from the skin that causes the allergic reaction. It’s important to do this as soon as possible after exposure to help prevent the spread of the oil to other areas of the body or to other people. After flushing the area, the nurse can then apply calamine lotion or recommend an oatmeal bath to help soothe the skin and relieve itching.

Answer: d. Apply suction in 3 to 4-second increments.

Rationale:

• a. Instill 2 mL of 0.9% sodium chloride prior to suctioning:While saline instillations may be used in some cases,it is not universally recommended for infants with tracheostomies and depends on the specific situation and healthcare provider's protocol.The priority in this case is to quickly clear the partial mucus occlusion to prevent respiratory distress.
• b. Select a catheter that fits snugly into the tracheostomy tube:This isincorrect.Selecting a catheter that fits tightly can damage the delicate tracheal mucosa and increase the risk of bleeding.A smaller-diameter catheter that allows for gentle passage is preferred.

• c. Use a clean technique when performing suctioning:This is absolutely essential for all suctioning procedures to minimize the risk of infection.However,it is not the specific action that addresses the immediate concern of clearing the partial mucus occlusion.
• d. Apply suction in 3 to 4-second increments:This is thecorrectapproach for suctioning an infant with a tracheostomy.Applying short,intermittent suction bursts minimizes the risk of hypoxia and tissue trauma while effectively removing secretions.

Therefore, the most important action for the nurse to take is to apply suction in short, 3-4 second bursts to effectively clear the mucus occlusion while minimizing risks to the infant.

Additional Points:

• The nurse should use sterile suction equipment and sterile technique throughout the procedure.
• The suction pressure should be set at the lowest effective level,typically 80-120 mmHg.
• The nurse should monitor the infant for signs of respiratory distress,such as increased work of breathing,retractions,and oxygen desaturation,before,during,and after suctioning.
• If the mucus occlusion is not cleared after several attempts,the nurse should seek assistance from ahealthcareprovider.

Answer: B. Reposition the probe every 2 hours.

Rationale:

• A. Warm the skin prior to probe placement:While cold fingers can lead to inaccurate readings,warming the skin is not an essential step and is not routinely recommended in clinical practice.
• B. Reposition the probe every 2 hours:This iscorrect.Continuous pressure from the probe in one spot can cause skin breakdown and pressure injuries.Repositioning the probe every 2 hours helps to prevent this and ensure accurate readings.
• C. Tape the wire to the palm of the hand:This is incorrect.The pulse oximeter probe should be placed on a vascular site,such as a fingertip or earlobe.Taping the wire to the palm would not provide accurate readings.
• D. Apply the sensor to the index fingernail:This is incorrect.The fingernail does not have sufficient blood flow for accurate pulse oximetry readings.The probe should be placed on the fleshy pad of the fingertip.

Therefore, the most important action for the nurse to take is to reposition the probe every 2 hours to prevent skin breakdown and ensure accurate readings.

Additional Points:

• The nurse should also choose a clean and dry site for probe placement.
• The probe should be snug but not too tight.
• The nurse should monitor the child for signs of skin breakdown,such as redness,swelling,or pain.
• If the child is restless or active,the nurse may need to secure the probe with additional tape or a special wrap.

Choice A rationale:
Extremities warm to the touch. This manifestation is not indicative of decreased cardiac output. Warm extremities suggest adequate peripheral perfusion and circulation. In a child with decreased cardiac output, the body might attempt to shunt blood away from the extremities to prioritize vital organs, leading to cooler extremities.
Choice B rationale:
Capillary refill 2 seconds. A capillary refill time of 2 seconds is within the normal range for a preschool-aged child. This quick capillary refill suggests adequate circulation and is not a sign of decreased cardiac output. Prolonged capillary refill time might be indicative of poor peripheral perfusion.
Choice C rationale:
Blood pressure 112/66 mm Hg. While a blood pressure of 112/66 mm Hg might be within the normal range for a preschooler, it is not the most reliable indicator of decreased cardiac output. Blood pressure can be influenced by various factors, and a seemingly normal blood pressure does not rule out decreased cardiac output if other manifestations are present.
Choice D rationale:
Diminished pulses. This is the correct choice. Diminished or weak pulses are indicative of decreased cardiac output. Inadequate blood volume being pumped by the heart can lead to reduced peripheral perfusion, resulting in diminished pulses. This sign is important in assessing the child's cardiovascular status postoperatively, especially after a corrective procedure for tetralogy of Fallot.

Choice A rationale:
Urine osmolality 500 mOsm/kg. Urine osmolality is a measure of urine concentration and is not a reliable indicator of infection. It reflects the kidney's ability to concentrate urine and can vary based on hydration status and other factors. An elevated urine osmolality could suggest dehydration, not necessarily infection.
Choice B rationale:
WBC 17,500/mm3. This is the correct choice. An elevated white blood cell count (WBC) is a hallmark sign of infection. The body's immune response to an infection often includes an increase in WBC count, particularly the neutrophil count. This elevation is known as leukocytosis and is a red flag for infection.
Choice C rationale:
BUN 12 mg/dL. Blood Urea Nitrogen (BUN) measures kidney function and hydration status. While an elevated BUN can indicate dehydration, it is not a specific marker for infection. BUN levels can be influenced by various factors, including diet and renal function.
Choice D rationale:
Urine specific gravity 1.014. Urine-specific gravity reflects the concentration of solutes in urine and the kidney's ability to concentrate or dilute urine. While changes in urine specific gravity can indicate dehydration or overhydration, it is not a direct indicator of infection. An infection is better detected through changes in WBC count and other clinical signs.

Choice A rationale:
Obtain the specimen by swabbing the infant's rectum using a sterile culture swab. This is the correct choice. When collecting a stool specimen from an infant, the rectal swab method is commonly used. A sterile culture swab helps prevent contamination and ensures accurate results for detecting the presence of ova and parasites in the stool.

Choice B rationale:
Place a urine collection device on the infant until the specimen is obtained. This choice is not appropriate for collecting a stool specimen. A urine collection device is used for collecting urine, not stool. The specimen for ova and parasites needs to be taken directly from the rectum or diaper to accurately identify any infestations.
Choice C rationale:
Transfer the specimen to the collection container using povidone-iodine-soaked gauze. While povidone-iodine is an antiseptic, it is not typically used to transfer stool specimens. Using a sterile swab or a clean, dry container is more suitable for collecting and transporting stool samples to the lab.
Choice D rationale:
Maintain the specimen at room temperature after collection until it is transferred to the lab. Stool specimens for ova and parasites usually require refrigeration to prevent the degradation and growth of potential pathogens. Room temperature might lead to the overgrowth of bacteria and parasites, affecting the accuracy of test results.

Choice A rationale:
Decrease daily oral fluid intake. Rationale: This choice is not appropriate for a client experiencing a vaso-occlusive crisis in sickle cell anemia. In this crisis, there is a risk of dehydration due to increased fluid loss, and decreasing oral fluid intake would exacerbate this issue. Adequate hydration is important to prevent further sickling of red blood cells and maintain organ perfusion.
Choice B rationale:
Maintain bed rest to prevent hypoxemia. Rationale: This is the correct choice. During a vaso-occlusive crisis in sickle cell anemia, blood flow to certain tissues is restricted, leading to tissue hypoxia and pain. Bed rest is recommended to reduce metabolic demands and oxygen consumption, helping to prevent further tissue damage and improve oxygenation. It also reduces the risk of complications such as thrombosis and respiratory compromise.
Choice C rationale:
Apply cold compresses to painful joints. Rationale: Applying cold compresses is not a recommended intervention for vaso-occlusive crisis in sickle cell anemia. Cold can exacerbate vasoconstriction and further compromise blood flow to the affected tissues. Warm compresses or warm baths might be more appropriate to promote vasodilation and alleviate pain.
Choice D rationale:
Administer meperidine to eliminate a fever. Rationale: Administering meperidine solely to eliminate a fever is not the primary focus of care for a vaso-occlusive crisis. The priority is to manage pain and improve tissue perfusion. Meperidine is an opioid analgesic that can be used to manage severe pain associated with sickle cell crises, but it should be given with caution due to the risk of respiratory depression and the potential for addiction.

Choice A rationale:
Gently lift the traction weights off the floor when repositioning the client. Rationale: This choice is not recommended in the care of a client in skeletal traction. Traction weights should never be lifted off the floor as they provide the necessary counter traction to align and immobilize the fractured bone. Lifting the weights could disrupt the traction and jeopardize the healing process.
Choice B rationale:
Reduce intake of foods containing fiber while nonambulatory. Rationale: While constipation can be a concern for clients in skeletal traction due to decreased mobility, reducing fiber intake is not the appropriate intervention. Adequate fiber intake is important to promote regular bowel movements and prevent constipation. Hydration and mobility exercises are more suitable approaches to manage constipation.
Choice C rationale:
Perform passive range-of-motion exercises to the affected extremity every 2 hours. Rationale: Passive range-of-motion exercises are important to maintain joint mobility and prevent muscle atrophy in a nonambulatory client. However, performing these exercises every 2 hours might be excessive and could cause unnecessary discomfort for the client. Range-of-motion exercises are usually done every 4 to 8 hours to strike a balance between maintaining joint health and providing rest.
Choice D rationale:
Apply protective padding to the end of the pin sites. Rationale: This is the correct choice. Applying protective padding to the end of the pin sites is crucial to prevent pressure ulcers and infection. The pin sites are potential entry points for bacteria, and protecting them helps reduce the risk of infection. Padding also prevents pressure on the skin and underlying tissues, reducing the potential for pressure injuries.

A history of frequent urinary tract infections (UTIs) is a sign of child maltreatment. It may indicate sexual abuse, which can introduce bacteria into the urinary tract.Sexual abuse may also cause genital or anal trauma, sexually transmitted infections, or pregnancy1. UTIs are uncommon in children, especially in boys.The normal frequency of UTIs in children is around 1 in 10 girls and 1 in 30 boys by the age of 16 years

Choice A rationale:
Encouraging active range of motion of the extremity is not recommended during the first 12 to 24 hours after a sprained wrist. Early movement can potentially worsen the swelling and delay the healing process.
Choice B rationale:
Applying warm compresses to the extremity is not the best choice to minimize swelling in the initial 12 to 24 hours after a sprained wrist. Heat can actually increase blood flow and promote more swelling in the injured area.
Choice C rationale:
Elevating the extremity above the level of the heart is the correct choice for minimizing swelling in the first 12 to 24 hours after a sprained wrist. Elevating the injured area helps to reduce blood flow to the area, which in turn decreases swelling and promotes healing.

Choice D rationale:
Wrapping the extremity loosely with an elastic bandage might be beneficial for providing support, but it's not the primary intervention for minimizing swelling in the first 12 to 24 hours after a sprained wrist. Elevation is more effective for reducing swelling during this initial period.
