Correct Answer: C

Rationale: The correct answer is C. A respiratory rate of 10/min indicates respiratory depression, a serious adverse effect of morphine that should be reported immediately. Options A, B, and D are within acceptable ranges and not indicative of life-threatening complications when administering morphine.

Correct Answer: A

Rationale: The correct first action for the nurse to take when preparing to administer a unit of packed RBCs is to check the client's identification band. This step is crucial to ensure that the correct blood is administered to the right client, preventing any errors or adverse reactions. Verifying the provider's prescription, priming the IV tubing, and obtaining the client's vital signs are important steps in the process but should follow the initial identification check to prioritize patient safety.

Correct Answer: B

Rationale: The correct answer is B: Decreased peripheral edema. Furosemide is a diuretic that helps in reducing fluid overload in clients with heart failure by increasing urine output. A decrease in peripheral edema indicates that the medication is effectively removing excess fluid from the body. Choices A, C, and D are incorrect because they do not indicate an improvement in the client's condition. Increased shortness of breath, increased jugular venous distention, and increased heart rate are all signs of worsening heart failure and would not be expected findings when furosemide is effective.

Correct Answer: A

Rationale: Correct! Frothy, pink sputum is a classic sign of pulmonary congestion in left-sided heart failure. This occurs due to the accumulation of fluid in the lungs, leading to the coughing up of frothy, pink-tinged sputum. Jugular vein distention (choice B) is more indicative of right-sided heart failure, where fluid backs up into the systemic circulation. Weight gain (choice C) may occur due to fluid retention, but it is not a direct manifestation of pulmonary congestion. Bradypnea (choice D) refers to abnormally slow breathing and is not specifically associated with pulmonary congestion.

Correct Answer: D

Rationale: The correct answer is D. Keeping the side rails of a toddler's crib elevated is an appropriate use of restraints to prevent the child from falling, which is an essential safety measure. Placing a belt restraint on a school-age child with seizures (choice A) is not recommended as it can be dangerous during a seizure. Securing wrist restraints to the bed rails for an adolescent (choice B) may cause harm and should not be done routinely. Applying elbow immobilizers to an infant receiving a cleft lip injury (choice C) is not a standard practice for managing this condition and would not be appropriate.
