Adult Health 1 Final Exam

Correct Answer: B

Rationale: When taking blood pressure at the brachial artery, it is crucial to place the client's arm at the level of the heart to ensure accurate measurement. Placing the arm above or below the heart level can lead to incorrect readings. Option A, placing the arm slightly above the heart level, would result in falsely lower blood pressure readings as gravity would assist in a lower value. Option C, placing the arm at a level of comfort for the client, may not align with the standardized technique required for accurate blood pressure assessment. Option D, placing the arm below the level of the heart, would likely yield falsely higher blood pressure readings due to increased hydrostatic pressure pushing the blood against gravity.

Correct Answer: A

Rationale: The correct answer is to use sunblock or protective clothing when outdoors. Methotrexate can cause photosensitivity, making the child more prone to sunburns and skin damage. Therefore, advising the parents to protect their child's skin from direct sunlight exposure is crucial. Choice B is incorrect because exposing the child to direct sunlight without protection can worsen the photosensitivity caused by methotrexate. Choice C is incorrect as obtaining vaccinations is generally avoided during chemotherapy due to the child's compromised immune system. Choice D is incorrect as commercial mouthwash may contain alcohol, which can be irritating to the child's oral mucosa, especially during chemotherapy.

Correct Answer: A

Rationale: The correct answer is A: Aspirin to prevent further blood clotting. Administering aspirin is crucial in the immediate management of a myocardial infarction as it helps prevent further blood clot formation, which is a key component in the treatment and prevention of myocardial infarction. Oxygen therapy (Choice B) is often provided, but aspirin takes precedence due to its role in reducing clot formation. Intravenous fluids (Choice C) may be needed but are not the immediate priority in this situation. Nitroglycerin (Choice D) is commonly used for chest pain relief in myocardial infarction but is not the first medication to be administered in this scenario.

Correct Answer: A

Rationale: During a severe asthma exacerbation, the nurse's priority is to administer a rescue inhaler immediately. This action helps open the airways and improve breathing, which is crucial in managing the exacerbation. Choice B, preparing for intubation, would be considered if the client's condition deteriorates and they are unable to maintain adequate oxygenation even after using the rescue inhaler. Encouraging deep breathing exercises (Choice C) may not be appropriate during a severe exacerbation as the client may struggle to breathe. While monitoring oxygen saturation levels (Choice D) is important, the immediate administration of a rescue inhaler takes precedence to address the acute breathing difficulty.

Correct Answer: D

Rationale: The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.
