LPN Pharmacology Practice Questions

Correct Answer: C

Rationale: The correct first action for the nurse to take is to check the client's status and lead placement. This step is crucial to ensure that the alarm is not triggered by a simple issue such as lead displacement. Calling a code blue (choice A) is premature without assessing the client first. Contacting the healthcare provider (choice B) can be done after ruling out basic causes for the alarm. Pressing the recorder button (choice D) is not as urgent as checking the client's status and lead placement in this scenario.

Correct Answer: B

Rationale: In a client with coronary artery disease (CAD) experiencing dyspnea at rest, the priority intervention should be to elevate the head of the bed to at least 45 degrees. This position helps reduce the work of breathing, optimizes lung expansion, and can alleviate symptoms of dyspnea by improving oxygenation and ventilation. Providing a walker for ambulation, monitoring oxygen saturation, and having an oxygen cannula at the bedside are important interventions but not the priority when the client is experiencing dyspnea at rest. Elevating the head of the bed is crucial to improve respiratory function and should be prioritized in this situation.

Correct Answer: C

Rationale: The most likely predisposing factor contributing to the proximal end of the femur fracture in a 62-year-old woman is osteoporosis resulting from declining hormone levels. Osteoporosis weakens the bones, making them more susceptible to fractures, especially in older adults, particularly women. In this case, the fracture can be attributed to the bone density loss associated with osteoporosis, which is a common concern in postmenopausal women. Choices A, B, and D are less likely to have directly contributed to the femur fracture in this scenario. Failing eyesight may increase the risk of falls but does not directly weaken the bones. Renal osteodystrophy affects bone health but is less common in this age group. Cerebral vessel changes causing transient ischemic attacks are related to vascular issues, not bone strength.

Correct Answer: B

Rationale: The correct next priority action after administering nitroglycerin to a client with CAD experiencing chest pain is to monitor the client's blood pressure. Nitroglycerin can cause hypotension, so it is crucial to assess and monitor the client's blood pressure for any signs of decreased perfusion or adverse effects. Obtaining a 12-lead ECG may be important but is not the immediate priority. Notifying the healthcare provider and administering a second dose of nitroglycerin should only be considered after ensuring the client's blood pressure is stable.

Correct Answer: B

Rationale: The correct technique for using a metered-dose inhaler (MDI) involves exhaling fully before inhaling deeply while pressing the canister to ensure effective delivery of the medication. Choice A is incorrect as exhaling should precede inhaling. Choice C is incorrect as taking two short breaths is not part of the correct technique. Choice D is incorrect as there is no need to hold the breath for a specific time after inhaling the medication.
