Correct Answer: A

Rationale: Administering oral antibiotics is within the scope of practice for an LPN and can be safely delegated. LPNs are trained to administer medications, including oral ones. Performing an admission assessment (Choice B) involves critical thinking and comprehensive evaluation, typically done by registered nurses. Creating new teaching material (Choice C) requires specialized knowledge and is usually the responsibility of a nurse with additional training in education. Administering IV conscious sedation (Choice D) is a high-risk task that requires advanced skills and should be performed by a registered nurse or higher-level provider.

Correct Answer: D

Rationale: The correct answer is D. Prednisone should never be stopped abruptly; it must be tapered down. Stopping it suddenly can lead to adrenal insufficiency. Choices A, B, and C are all potential side effects or considerations when taking prednisone and do not indicate a need for further teaching.

Correct Answer: B

Rationale: The correct answer is B: Driving a car. Driving a car can be physically and emotionally taxing, increasing the risk of complications soon after a myocardial infarction. It requires quick reflexes and decision-making abilities, which may be impaired during the recovery period. Swimming in a pool, light housework, and walking on flat ground are generally safe and beneficial activities for clients following a myocardial infarction as they promote circulation, muscle strength, and overall well-being.

Correct Answer: A

Rationale: The correct answer is A: Pregnancy status. Raloxifene is a pregnancy category X drug, which means it can cause serious birth defects. Therefore, it is crucial for the nurse to assess the client's pregnancy status before initiating therapy. Choice B, bone density, while important in osteoporosis management, is not a specific concern related to initiating raloxifene therapy. Choice C, calcium levels, and choice D, blood pressure, are not directly related to the initiation of raloxifene therapy in a female client with osteoporosis.

Correct Answer: B

Rationale: The correct nursing interventions for a patient with pneumonia include monitoring lung sounds and respiratory rate to assess the effectiveness of treatment and the patient's respiratory status. Providing fluids and rest (Choice A) can be supportive measures but are not specific nursing interventions for pneumonia. Encouraging coughing and deep breathing exercises (Choice C) can be helpful for airway clearance but may not be appropriate for all patients with pneumonia. Administering antibiotics and providing oxygen therapy (Choice D) are medical interventions rather than nursing interventions.
