Correct Answer: B

Rationale: Palpating the pulse distal to the cast is the priority as it assesses for circulation. Ensuring adequate blood flow is essential to prevent complications such as compartment syndrome. Placing an ice pack over the cast could cause constriction of blood vessels, further compromising circulation. Teaching the client about cast care and positioning the casted extremity on a pillow are important but do not take precedence over assessing circulation.

Correct Answer: A

Rationale: The correct answer is A. Taking omeprazole before meals is important as it improves the medication's effectiveness in reducing gastric acid production. Option B is incorrect as omeprazole should not be taken with antacids as it can interfere with its absorption. Option C is incorrect because omeprazole is usually recommended to be taken before breakfast, not at bedtime. Option D is incorrect as omeprazole is generally taken on an empty stomach, at least 1 hour before a meal.

Correct Answer: C

Rationale: Administering anticoagulants as prescribed is a crucial intervention for clients with pulmonary embolism to prevent further clot formation. Encouraging the client to ambulate frequently may dislodge the clot and lead to worsening symptoms. Placing the client in a prone position can compromise respiratory function. Initiating seizure precautions is not directly related to the management of pulmonary embolism.

Correct Answer: B

Rationale: The correct answer is B because a new onset of tachypnea can indicate a respiratory complication, which requires immediate assessment. Sinus arrhythmia, epidural analgesia with weakness, and a hemoglobin A1C level of 6.8% in a client with diabetes do not pose immediate life-threatening concerns that require urgent assessment compared to the potential respiratory issues associated with tachypnea.

Correct Answer: B

Rationale: The correct action for the nurse to take when caring for a client with alcohol use disorder experiencing withdrawal is to administer diazepam. Diazepam is a benzodiazepine commonly used to manage withdrawal symptoms in these clients by reducing anxiety, tremors, and the risk of seizures. Administering naloxone (Choice A) is used for opioid overdose, not alcohol withdrawal. Encouraging oral fluid intake (Choice C) is generally beneficial but not a specific intervention for alcohol withdrawal. Administering magnesium sulfate (Choice D) is not indicated for alcohol withdrawal but may be used for other conditions like preeclampsia or eclampsia.
