Correct Answer: B

Rationale: The correct instruction for a client with GERD is to avoid drinking fluids with meals. This is because consuming fluids while eating can exacerbate reflux symptoms by increasing stomach distension and contributing to the reflux of stomach contents into the esophagus. Option A is incorrect as elevating the head of the bed can help prevent reflux during sleep, not while drinking fluids. Option C is incorrect as consuming three large meals a day can worsen GERD symptoms due to increased gastric distension. Option D is incorrect as lying down after eating can also worsen GERD symptoms by promoting the reflux of stomach contents into the esophagus.

Correct Answer: B

Rationale: The correct answer is B: 'Serum calcium level of 8.0 mg/dL.' A low serum calcium level indicates hypocalcemia, which is a potential complication of thyroidectomy that can lead to life-threatening consequences, such as tetany or laryngospasm. Therefore, it is crucial for the nurse to report this finding promptly to the provider for timely intervention. Choices A, C, and D are important assessments following a thyroidectomy but are not as critical as detecting and addressing hypocalcemia, which can have serious implications for the client's health.

Correct Answer: B

Rationale: Providing oral glucose is the correct intervention for a patient experiencing hypoglycemia. Oral glucose helps quickly raise blood sugar levels, making it the preferred treatment for mild hypoglycemia. Administering glucagon (Choice A) is usually reserved for severe cases when the patient cannot take anything by mouth. Administering IV fluids (Choice C) is not the primary intervention for hypoglycemia unless the patient is severely dehydrated. Monitoring blood sugar levels (Choice D) is important but providing glucose is the immediate priority to treat hypoglycemia.

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: A

Rationale: The correct answer is A: Administer oxygen. Administering oxygen is the priority intervention for a patient with a suspected pulmonary embolism to improve oxygenation levels. In pulmonary embolism, there is a blockage in one of the pulmonary arteries, leading to decreased oxygen exchange. Administering oxygen helps increase oxygen saturation levels. Anticoagulants (Choice B) are essential in the treatment of pulmonary embolism but are not the initial priority intervention. Surgery (Choice C) is not typically the first-line treatment for pulmonary embolism. Monitoring oxygen saturation (Choice D) is important but administering oxygen takes precedence as the immediate action to address hypoxemia.
