Correct Answer: B

Rationale: The most appropriate initial nursing action when a client develops a rash and itching while receiving intravenous antibiotics is to discontinue the antibiotic infusion. This is crucial to prevent further allergic reactions. Administering diphenhydramine (Benadryl) (Choice A) can be considered after discontinuing the antibiotic infusion. Applying a cool compress to the rash (Choice C) may provide symptomatic relief but does not address the underlying cause. Notifying the healthcare provider (Choice D) is important but should come after discontinuing the antibiotic infusion to ensure the client's safety.

Correct Answer: B

Rationale: The correct action when assessing an immobile patient for deep vein thromboses (DVTs) is to measure the calf circumference of both legs. This helps in detecting swelling or changes that may indicate the presence of a DVT. Removing elastic stockings every 4 hours (Choice A) is not necessary and can disrupt circulation. Lightly rubbing the lower leg for redness and tenderness (Choice C) can potentially dislodge a clot if present. Dorsiflexing the foot while assessing for patient discomfort (Choice D) is not a specific assessment for DVT and may not provide relevant information in this context.

Correct Answer: C

Rationale: The correct task that a healthcare provider should delegate to assistive personnel is performing a simple dressing change. Assistive personnel are trained and competent in performing basic wound care activities like simple dressing changes. Evaluating the healing of an incision requires clinical judgment and assessment skills that are typically performed by licensed healthcare professionals, such as nurses or physicians. Inserting an NG tube and changing IV tubing involve invasive procedures that require specialized training and skills, making them tasks that should be performed by licensed healthcare providers rather than assistive personnel.

Correct Answer: A

Rationale: The most important action for the LPN/LVN to take when a client with a history of diabetes mellitus experiences symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps assess the severity of hyperglycemia and guides further interventions. Encouraging the client to increase fluid intake (Choice B) may exacerbate the symptoms by further diluting the blood glucose concentration. Administering insulin as prescribed (Choice C) should be done based on the healthcare provider's orders and after assessing the blood glucose levels. Assessing the client's urine output (Choice D) is important but not the most immediate action needed in this scenario.

Correct Answer: A

Rationale: Before administering morphine sulfate, it is crucial to measure the client's vital signs to ensure that the client is stable and safe to receive the medication. This step helps identify any contraindications or abnormalities that could affect the administration of morphine. Assessing the client's pain level (choice B) is important, but ensuring the client's physiological stability takes precedence. Verifying the morphine order with another nurse (choice C) and checking the client's last dose of morphine (choice D) are important steps but are not the priority before administering the medication.
