A client who weighs 176 pounds receives a prescription for norepinephrine 2 mcg/min intravenously (IV). The IV bag is labeled, "Norepinephrine 4 mg in dextrose 5% in water (D;W) 1,000 mL." How many mL/hour should the nurse program the infusion pump? (Enter numerical value only.).
The Correct Answer is ["30"]
The correct answer is 30 mL/hour.
Step 1 is to calculate the total amount of norepinephrine in the IV bag: 4 mg norepinephrine ÷ 1000 mL = 0.004 mg/mL
Step 2 is to convert the patient's weight from pounds to kilograms: 176 pounds ÷ 2.2 = 80 kilograms
Step 3 is to calculate the total amount of norepinephrine the patient will receive per minute: 2 mcg/min × 60 min = 120 mcg/min
Step 4 is to convert micrograms (mcg) to milligrams (mg): 120 mcg ÷ 1000 = 0.12 mg
Step 5 is to calculate the total volume of norepinephrine needed per hour: 0.12 mg ÷ 0.004 mg/mL = 30 mL/hour
Therefore, the nurse should program the infusion pump to deliver 30 mL/hour.

Correct Answer is A
Explanation
A - The injury may require medical attention, as the mother mentioned that the boy is in pain. Correct
This is the correct answer, as it reflects the nurse's assessment of the injury and the appropriate action to take. The nurse should consider the mother's report of pain as a valid indicator of the severity of the injury, and should not dismiss or minimize it.
The nurse should also observe the boy's arm and shoulder for any signs of fracture, dislocation, swelling, bruising, or deformity, and ask him to rate his pain on a scale of 0 to 10. The nurse should then decide whether to refer the boy to a physician or an emergency department for further evaluation and treatment.
B - The abrasions on the boy's leg and hand have healed.
This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The abrasions on the boy's leg and hand are not relevant to his current complaint of arm and shoulder pain, and do not indicate whether he needs medical attention or not. The nurse should focus on the boy's primary concern and not distract him with unrelated questions or comments.
C - The mother describes what she did after her child got injured.
This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The mother's description of what she did after her child got injured may provide some useful information, such as how long ago the injury occurred, what first aid measures were applied, and whether there was any improvement or worsening of symptoms. However, it does not directly answer the question of whether the injury requires medical attention or not. The nurse should listen to the mother's account, but also perform a physical examination and ask relevant questions to assess the injury.
D - The boy lacks coordination when answering the nurse's questions.
This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The boy's lack of coordination when answering the nurse's questions may indicate a possible head injury, concussion, or shock, which are serious complications that require immediate medical attention. However, it does not directly relate to his arm and shoulder pain, which is his main complaint.
The nurse should assess the boy's mental status and neurological function, but also evaluate his arm and shoulder for any signs of damage or inflammation.
Correct Answer is A
Explanation
Based on the provided audio clip, the sound heard is a high-pitched, continuous, musical sound. This sound is characteristic of wheezing, which is caused by the narrowing of the airways due to inflammation, bronchoconstriction, or the presence of mucus. Wheezing is commonly associated with conditions such as asthma, chronic obstructive pulmonary disease (COPD), or bronchitis.
Let's evaluate the other options:
b) Rhonchi: Rhonchi are low-pitched, coarse, ratling sounds that typically indicate the presence of mucus or fluid in the larger airways. Rhonchi are often heard in conditions such as pneumonia or bronchitis, but they are different from the high-pitched wheezing sound heard in the audio clip.
c) Stridor: Stridor is a high-pitched, harsh, and crowing sound that is heard during inspiration. It is often associated with upper airway obstruction, such as in cases of croup, epiglottitis, or a foreign body obstruction. The sound in the audio clip does not match the characteristics of stridor.
d) Fine crackles: Fine crackles are discontinuous, high-pitched, and brief sounds that are typically heard during inspiration. They are often described as "velcro-like" or "rice crispies" and are associated with conditions such as pulmonary fibrosis or congestive heart failure. The sound in the audio clip does not resemble fine crackles.
In summary, the sound in the provided audio clip is best described as wheezing, characterized by a high- pitched, continuous, musical sound. Therefore, the practical nurse (PN) should document this sound as "wheeze."
