Correct Answer: C

Rationale: The correct answer is C: Excess fluid volume. This patient is presenting with signs and symptoms of fluid overload, such as weight gain, pitting edema, distended neck veins, and crackles in the lungs. These indicate an excess of fluid in the body. Nursing care for this patient should focus on managing fluid balance. A: Deficient fluid volume is incorrect because the patient is showing signs of fluid overload, not deficit. B: Imbalanced nutrition more than body requirements is incorrect as the symptoms described are related to fluid volume, not nutrition intake. D: Noncompliance is irrelevant to the patient's current symptoms and does not address the underlying issue of fluid overload.

Correct Answer: B

Rationale: The correct answer is B: The potential complication. In a collaborative problem, the focus of a diagnostic statement should be on identifying potential complications that may arise due to the client's health issue. This is important for developing effective interventions to prevent or manage these complications. Choice A focuses on the client's problem itself, not on potential complications. Choice C is related to nursing diagnosis, not collaborative problems. Choice D refers to medical diagnosis, which is different from collaborative problems involving nursing and other healthcare disciplines. Therefore, B is the correct focus for a diagnostic statement in a collaborative problem scenario.

Correct Answer: C

Rationale: The correct answer is C: severe dehydration. In HHNK coma, the body tries to eliminate excess glucose through frequent urination, leading to dehydration. This results in decreased blood volume, causing hypotension and tachycardia. Signs include dry mucous membranes, poor skin turgor, and concentrated urine output. Fruity odor of the breath (A) is associated with diabetic ketoacidosis, not HHNK coma. Shallow, deep respirations (B) and profuse sweating (D) are not typically associated with HHNK coma.

Correct Answer: C

Rationale: Rationale: C: 0.25 mg is the correct daily dosage of Digoxin for adults with heart failure. This dosage is within the usual range of 0.125-0.25 mg. It helps improve heart function and manage heart failure symptoms. A: 0.005 mg is too low and ineffective. B: 0.025 mg is also too low for therapeutic effect. D: 2.5 mg is too high and may lead to toxicity in most adult patients.

Correct Answer: C

Rationale: The correct answer is C because the patient expressing fear of going home and being alone indicates apprehension about discharge. This is supported by stable vital signs and nearly healed incision, suggesting physical recovery. Choice A is incorrect as fear of being alone does not necessarily mean the patient can perform dressing changes independently. Choice B is incorrect as resuming medications is not related to the patient's fear of being alone. Choice D is incorrect as there is no evidence to suggest the surgery was unsuccessful based on the information provided.
