Adult Health 1 Final Exam

Correct Answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

Correct Answer: B

Rationale: Providing frequent oral care is crucial when a client is NPO to ensure comfort and prevent drying of the oral mucosa. In this situation, the priority is maintaining oral hygiene to prevent complications such as oral mucosa breakdown. Monitoring bowel sounds may be important in assessing bowel activity, but it is not the priority when the client is NPO due to a small bowel obstruction. Encouraging ambulation can be beneficial for other conditions, but in this case, oral care takes precedence. Measuring abdominal girth is more relevant for assessing abdominal distention, which is not the priority when the client is NPO. Therefore, the most important nursing intervention is to provide frequent oral care.

Correct Answer: D

Rationale: The most crucial aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is essential to detect early signs of complications such as ischemia or infection. Changing the colostomy bag daily is important but not as critical as assessing the stoma for complications. Irrigating the colostomy daily is not a standard recommendation and should be performed based on healthcare provider's instructions. While avoiding high-fiber foods may be beneficial for some individuals with a colostomy, it is not the most important aspect of care compared to monitoring the stoma for complications.

Correct Answer: A

Rationale: Cushingoid side effects are characteristic of excess corticosteroid use, such as dexamethasone. These include moon face (rounding of the face), slow wound healing, muscle wasting, and sodium and water retention. Options B, C, and D describe symptoms that are not typically associated with Cushingoid side effects. Tachycardia, hypertension, weight loss, heat intolerance, nervousness, restlessness, tremor (Option B) are not typical of Cushingoid effects, while bradycardia, weight gain, cold intolerance, myxedema facies, and periorbital edema (Option C) are more indicative of hypothyroidism. Hyperpigmentation, hyponatremia, hyperkalemia, dehydration, and hypotension (Option D) are not classical features of Cushingoid side effects.

Correct Answer: B

Rationale: The most crucial dietary restriction to emphasize for a client with chronic kidney disease (CKD) is to restrict protein intake. By restricting protein intake, the workload on the kidneys is reduced, which helps slow the progression of CKD. While high-fiber foods are generally beneficial, they may need to be limited in some individuals with CKD due to potassium concerns, making choice A less critical. Avoiding dairy products may be necessary in some cases to control phosphorus levels, but it is not as vital as restricting protein intake. Increasing fluid intake is essential for kidney health, but it is not the most critical dietary modification for clients with CKD.
