A child with a known history of asthma is admitted to the hospital with a respiratory infection. Which action is the nurse's priority?
- A. Administer a nebulizer treatment as ordered.
- B. Perform chest physiotherapy.
- C. Monitor oxygen saturation levels closely.
- D. Educate the parents about infection prevention.
Correct Answer: A
Rationale: The priority in asthma management is ensuring the airways are open, which is best achieved by administering a nebulizer treatment as ordered.

Renin:
- A. Is secreted mainly in extrarenal tissues
- B. Secretion increases on lying supine
- C. Secretion increases with potassium
- D. Converts angiotensin I into angiotensin II
Correct Answer: D
Rationale: Renin is an enzyme produced by the kidneys that converts angiotensin I into angiotensin II which plays a key role in regulating blood pressure and fluid balance. The other options are incorrect because renin is not mainly secreted in extrarenal tissues its secretion does not increase on lying supine or with potassium and it does not regulate osmolality.
The nurse reports that a client is at risk for a brain attack (stroke) based on which assessment finding?
- A. Nuchal rigidity
- B. Carotid bruit
- C. Jugular vein distention
- D. Palpable cervical lymph node
Correct Answer: B
Rationale: A carotid bruit indicates turbulent blood flow, which is a risk factor for stroke.
A nursing action that promotes ideal nutrition in an infant with congestive heart failure (CHF) is:
- A. Feeding formula that is supplemented with additional calories.
- B. Allowing the infant to nurse at each breast for 20 minutes.
- C. Providing large feedings every 5 hours.
- D. Using firm nipples with small openings to slow feedings.
Correct Answer: A
Rationale: Supplementing formula with extra calories increases the caloric density to support growth in infants with CHF.
What does the surgical closure of the ductus arteriosus do?
- A. Stop the loss of unoxygenated blood to the systemic circulation
- B. Decrease the edema in legs and feet
- C. Increase the oxygenation of blood
- D. Prevent the return of oxygenated blood to the lungs
Correct Answer: D
Rationale: The ductus arteriosus allows blood to flow from the higher-pressure aorta to the lower-pressure pulmonary artery, causing a right-to-left shunt. If this is surgically closed, no additional oxygenated blood (from the aorta) will return to the lungs through the pulmonary artery. The aorta carries oxygenated blood to the systemic circulation. Because of the higher pressure in the aorta, blood is shunted into the pulmonary artery and the pulmonary circulation. Edema in the legs and feet is usually a sign of heart failure. This repair would not directly affect the edema. Increasing the oxygenation of blood would not interfere with the return of oxygenated blood to the lungs.

- A. congenital mitral stenosis
