Adult Health 1 Final Exam

Correct Answer: A

Rationale: The correct answer is A: Hyponatremia. Lithium can affect sodium levels in the body, potentially leading to hyponatremia, which is a condition characterized by low sodium levels. This imbalance requires close monitoring as it can lead to symptoms such as confusion, weakness, and even seizures. Choices B, C, and D are incorrect because lithium is not primarily associated with causing hypokalemia, hypercalcemia, or hypernatremia. While these imbalances can occur in certain conditions or with other medications, the main electrolyte imbalance to monitor when a client is prescribed lithium is hyponatremia.

Correct Answer: A

Rationale: Continuous bubbling in the water seal chamber should be reported to the healthcare provider immediately. This finding may indicate an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Absence of drainage in the collection chamber (choice B) may signify that the chest tube is blocked, but it does not pose an immediate threat to the client's condition. Tidaling in the water seal chamber (choice C) is an expected finding and indicates proper functioning of the chest tube system. Presence of subcutaneous emphysema around the insertion site (choice D) suggests air leakage but is not as urgent as continuous bubbling in the water seal chamber.

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 correct answer is B. Maintaining a consistent intake of vitamin K-rich foods is important for patients taking warfarin as it helps keep the effects of the medication stable. Choice A is incorrect because while green leafy vegetables are high in vitamin K, they should not be avoided completely but rather consumed consistently. Choice C is also incorrect as avoiding all foods containing vitamin K can lead to fluctuations in warfarin's effectiveness. Choice D is incorrect as a high-protein diet is not specifically recommended for patients taking warfarin.

Correct Answer: B

Rationale: The correct initial intervention for a client with chronic heart failure presenting with dyspnea and fatigue is oxygen therapy. Oxygen therapy can help relieve dyspnea and improve oxygen saturation levels, which are crucial in managing heart failure exacerbations. Administering IV diuretics may be necessary later to address fluid overload, but oxygen therapy takes precedence in addressing the immediate respiratory distress. Bed rest and dietary consultation are important aspects of care for heart failure patients, but in this scenario, oxygen therapy is the priority to improve the client's respiratory status.
