An adolescent arrives at the emergency department (ED) with a fever and persistent lower right quadrant abdominal pain.
The patient is anxious, fearful, and hyperventilating.
What acid-base imbalance does the nurse anticipate the patient will develop?
Respiratory alkalosis.
Respiratory acidosis.
Metabolic alkalosis.
Metabolic acidosis.
The Correct Answer is A
Choice A rationale
Hyperventilation leads to a decrease in the amount of carbon dioxide (CO2) in the blood. This causes the pH of the blood to increase, resulting in respiratory alkalosis.
Choice B rationale
Respiratory acidosis is caused by a buildup of CO2 in the blood, typically due to hypoventilation (under-breathing). This is not consistent with the patient’s symptoms of hyperventilation.
Choice C rationale
Metabolic alkalosis is typically caused by a significant loss of acid from the body, such as from prolonged vomiting. This is not consistent with the patient’s symptoms.
Choice D rationale
Metabolic acidosis is typically caused by an increase in acid production within the body or a loss of bicarbonate from the body, such as in diabetic ketoacidosis or kidney disease. This is not consistent with the patient’s symptoms.

Correct Answer is A
Explanation
Choice A rationale
A firm crib mattress is crucial in reducing the risk of Sudden Infant Death Syndrome (SIDS). Soft surfaces can conform to the infant’s face and potentially block their airway, leading to suffocation.
Choice B rationale
Propping the infant with a pillow when in a side-lying position is not recommended as it increases the risk of SIDS. Infants should always be placed on their backs to sleep.
Choice C rationale
Swaddling the infant in a blanket for sleeping is not the most important measure to prevent SIDS. Overheating and loose bedding are risk factors for SIDS23.
Choice D rationale
Placing the infant in a prone position whenever possible is not recommended. Infants should always be placed on their backs to sleep to reduce the risk of SIDS23.
Correct Answer is ["1.80"]
Explanation
Step 1 is to convert the patient’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.20462 pounds. So, the patient’s weight in kilograms is 132 pounds ÷ 2.20462 = 59.87 kg.
Step 2 is to calculate the total dosage of dantrolene needed. The prescribed dosage is 1.5 mg/kg. So, the total dosage is 1.5 mg/kg × 59.87 kg = 89.81 mg.
Step 3 is to calculate the volume of reconstituted dantrolene solution needed to provide the total dosage. The reconstituted solution has a concentration of 50 mg/mL. So, the volume needed is 89.81 mg ÷ 50 mg/mL = 1.80 mL.
