Correct Answer: A

Rationale: The priority nursing action for a patient with respiratory distress is to administer oxygen. Oxygen therapy is crucial in improving oxygenation levels and relieving respiratory distress, making it the top priority intervention. Repositioning the patient, administering bronchodilators, or providing chest physiotherapy may be necessary interventions depending on the underlying cause, but ensuring adequate oxygen supply should take precedence in addressing respiratory distress.

Correct Answer: A

Rationale: Administering oxygen is crucial for a patient presenting with confusion after surgery because it helps alleviate potential hypoxia, which can be a common cause of confusion in the postoperative period. While repositioning the patient, administering IV fluids, and performing a neurological assessment are important nursing interventions in certain situations, addressing hypoxia by administering oxygen takes priority in this case to ensure an adequate oxygen supply to the brain and other vital organs.

Correct Answer: C

Rationale: When administering enoxaparin for the prevention of DVT, the nurse should inject the medication into the lateral abdominal wall. This site is preferred for subcutaneous injections of enoxaparin to reduce the risk of bleeding or injury. Expelling air bubbles, massaging the injection site, or administering an NSAID for discomfort are not appropriate actions and could lead to complications or ineffective medication delivery.

Correct Answer: D

Rationale: Corrected Rationale: Decreased deep tendon reflexes are a common finding in clients with hypothyroidism due to slowed metabolic processes. The other choices, such as bradycardia (slow heart rate), weight gain, and hypertension (high blood pressure) are not typically associated with hypothyroidism. Bradycardia can occur due to the decreased metabolic rate, but it is not a consistent finding. Weight gain is common but not universal, and hypertension is more commonly associated with hyperthyroidism.

Correct Answer: D

Rationale: A urine output of 25 mL/hr is a sign of oliguria, which may indicate dehydration or kidney impairment and should be reported. A heart rate of 90/min is within the normal range (60-100/min) for adults at rest and may be expected postoperatively. A temperature of 37.1°C (98.8°F) is within the normal range (36.1-37.2°C or 97-99°F) and does not indicate an immediate concern. Serosanguineous wound drainage is a common finding postoperatively and indicates a normal healing process.
