Correct Answer: D

Rationale: The correct answer is D. A client who had an abdominal-perineal resection 2 days ago with no drainage on the dressing but is presenting with fever and chills requires immediate attention. This presentation raises concerns for peritonitis, a serious complication that necessitates prompt assessment and intervention to prevent further complications. Choices A, B, and C do not indicate an immediate risk for a life-threatening condition like peritonitis, making them lower priority compared to choice D.

Correct Answer: A

Rationale: The correct answer is to advise the client to come to the clinic to be seen by a healthcare provider. Persistent vomiting during pregnancy can lead to dehydration, which requires medical evaluation. Choice B is incorrect because solely increasing fluid intake and resting at home may not be sufficient to address the potential dehydration and underlying causes of vomiting. Choice C is not recommended without medical evaluation, as over-the-counter antiemetics should be used under healthcare provider guidance during pregnancy. Choice D is not the best option here because with persistent vomiting and risk of dehydration, immediate medical assessment is crucial to ensure the well-being of both the client and the fetus.

Correct Answer: C

Rationale: The correct answer is C. The use of accessory muscles is most concerning in a client with COPD receiving supplemental oxygen as it indicates increased work of breathing, requiring immediate intervention. Oxygen saturation of 90% is acceptable in a client with COPD. A respiratory rate of 24 breaths per minute is slightly elevated but not as critical as the use of accessory muscles. Inspiratory crackles may be present in clients with COPD due to underlying lung changes but do not require immediate intervention unless associated with other concerning symptoms.

Correct Answer: C

Rationale: A positive Chvostek's sign is the most concerning assessment finding as it suggests hypocalcemia, which is a potential complication following thyroidectomy. Hypocalcemia can lead to serious complications such as tetany and laryngospasm. Immediate intervention is required to prevent further complications. Choices A, B, and D are common post-thyroidectomy findings and are expected during the immediate postoperative period. Slight difficulty swallowing may be due to postoperative swelling, a hoarse voice may be temporary due to intubation trauma, and pain at the incision site is normal after surgery.

Correct Answer: B

Rationale: In this scenario, the client's symptoms of nausea and a significant drop in blood pressure suggest a potential right ventricular infarction. The appropriate intervention for this situation is to infuse a rapid IV normal saline bolus. This fluid resuscitation helps improve cardiac output by increasing preload, which can be beneficial in right ventricular infarction. Administering a second dose of nitroglycerin may further lower blood pressure. External chest compressions are not indicated in this case as the client has a pulse. Providing an antiemetic medication does not address the underlying issue of hypotension and potential right ventricular involvement.
