Correct Answer: B

Rationale: The correct interventions to include when a client with heart failure is being treated with diuretics for fluid volume excess are to observe for evidence of hypokalemia. Diuretics can lead to potassium loss, resulting in hypokalemia. Monitoring for this electrolyte imbalance is crucial. Encouraging oral fluid intake of 3,000 ml/day may exacerbate fluid volume excess in a client with heart failure. Teaching the client how to restrict dietary sodium is important in managing heart failure, but it is not directly related to the use of diuretics for fluid volume excess. Monitoring PTT, PT, and INR lab values is not typically associated with diuretic therapy for heart failure but rather with anticoagulant therapy.

Correct Answer: B

Rationale: Asymmetry of the shoulders when standing upright is a common indicator of scoliosis. This finding suggests a possible spinal abnormality and should prompt further evaluation. Choices A, C, and D are not specific indicators of scoliosis. Inability to touch their toes may indicate flexibility issues or tightness in the hamstrings. Audible crepitus when bending may suggest joint degeneration or inflammation. An exaggerated upper thoracic convex curvature could indicate poor posture or other spinal abnormalities but is not directly indicative of scoliosis.

Correct Answer: B

Rationale: The correct answer is B: Worming movements of the tongue. Worming movements of the tongue, known as tardive dyskinesia, are an irreversible side effect of antipsychotic medications. Tardive dyskinesia is characterized by involuntary, repetitive movements of the tongue, lips, face, trunk, and extremities. Cramping muscular pain (Choice A) is more indicative of dystonia, an extrapyramidal side effect that can be treated effectively with antiparkinsonian medications. Decreased tendon reflexes (Choice C) are not typically associated with irreversible side effects of antipsychotic agents. Dry oral mucous membranes (Choice D) are not specific to irreversible side effects of antipsychotic medications.

Correct Answer: C

Rationale: The correct answer is C. Some salt substitutes can be high in potassium, which may not be suitable for clients with heart failure. Option A is correct as using lemon juice and herbs for flavoring is a good low-sodium alternative. Option B is also correct as canned soups and frozen dinners are typically high in sodium content. Option D is correct as checking food labels for sodium content is an essential part of managing a low-sodium diet. Therefore, the client's statement about using salt substitutes needs correction as it can introduce high levels of potassium, which may not be recommended for individuals with heart failure.

Correct Answer: C

Rationale: The correct answer is C because a significant difference in calf circumference between the legs is a classic sign of DVT. This is due to the obstruction of blood flow in the deep veins of the leg, leading to swelling in the affected limb. Choices A, B, and D are not typical findings of DVT. Choice A describes a neurological response, choice B indicates a bruise on the right calf, and choice D describes pitting edema in both lower extremities, which are not specific signs of DVT.
