Correct Answer: C

Rationale: The correct answer is C, warmth and redness in the calf. These symptoms may indicate a deep vein thrombosis (DVT), a serious complication following hip arthroplasty that requires immediate attention. A heart rate of 90/min and blood pressure of 118/76 mm Hg are within normal ranges for a postoperative client and do not indicate an urgent issue. Pink-tinged urine may suggest blood in the urine, which should be monitored but is not as critical as the potential DVT.

Correct Answer: C

Rationale: The correct action for the nurse to take in this situation is to discontinue the oxytocin infusion. With contractions occurring every 2 minutes and lasting 90 seconds, this pattern indicates hyperstimulation, which can be harmful to the fetus. Discontinuing the oxytocin infusion is essential to prevent further harm. Increasing the oxytocin infusion would exacerbate the situation, maintaining it would continue the risk, and providing reassurance to the client, although important, does not address the need for immediate action to ensure the safety of the fetus.

Correct Answer: A

Rationale: The correct answer is to assess the patient for injuries. When a patient experiences a fall in the hospital, the immediate concern is to check for any injuries that may require urgent care. Calling for help can be done after assessing the patient to ensure appropriate assistance is provided. Documenting the fall is important for the patient's medical record, but it is not the most immediate action needed. Notifying the healthcare provider can come after the initial assessment to update them on the situation.

Correct Answer: A

Rationale: The correct answer is to administer bronchodilators as the priority nursing intervention for a patient with an acute asthma attack. Bronchodilators help open the airways and improve airflow, which is crucial in managing acute asthma symptoms. Administering corticosteroids (Choice B) is also important in the treatment plan, but it is not the priority intervention during an acute attack. Providing supplemental oxygen (Choice C) may be necessary but is not the priority initial intervention. Starting IV fluids (Choice D) is not typically indicated as a priority intervention for an acute asthma attack.

Correct Answer: A

Rationale: When educating a client about nutritional intake, it is important to mention that carbohydrates should constitute at least 45% of their daily caloric intake for a balanced diet. This macronutrient provides energy and is essential for proper bodily functions. Choice B is incorrect because protein should typically account for around 10-35% of total caloric intake, not 55%. Choice C is too low for the recommended carbohydrate intake, as it should be higher at 45%. Choice D is incorrect as protein intake should generally be around 10-35% of total caloric intake, not 60%.
