Correct Answer: C

Rationale: The correct answer is C: Clear lung sounds. Clear lung sounds indicate a therapeutic effect of furosemide, as the medication helps reduce fluid overload in heart failure. Choice A, increased shortness of breath, is incorrect as furosemide is used to relieve symptoms like shortness of breath. Choice B, weight gain of 2.3 kg (5 lb), is incorrect as furosemide is a diuretic that helps reduce fluid retention leading to weight loss. Choice D, bounding pulse, is incorrect as furosemide does not directly impact the pulse rate.

Correct Answer: C

Rationale: The correct precaution to implement when caring for a client with Clostridium difficile infection is to wear a gown and gloves when providing care. Clostridium difficile is primarily spread through contact with feces, so wearing personal protective equipment like gowns and gloves is crucial in preventing the spread of the infection. Placing the client in a negative pressure room (Choice A) is not necessary for Clostridium difficile. While wearing an N95 respirator mask (Choice B) is important for airborne precautions, it is not required for Clostridium difficile. Placing a face mask on the client (Choice D) is not a standard precaution for preventing the spread of Clostridium difficile.

Correct Answer: B

Rationale: The correct answer is B: "You should restrict your fluid intake to 1 liter per day." Clients with heart failure should limit their fluid intake to prevent fluid overload, which can worsen their condition. Choice A is incorrect because 2 liters of water per day may be excessive for someone with heart failure. Choice C is incorrect as unlimited fluid intake is not suitable for individuals with heart failure. Choice D is also incorrect as 3 liters per day may be too much fluid for a client with heart failure.

Correct Answer: B

Rationale: The correct action the nurse should take when administering enoxaparin is to inject the medication deep into subcutaneous tissue. This method helps ensure proper absorption of the medication and prevents tissue irritation. Injecting into the deltoid muscle (Choice A) is not recommended for enoxaparin administration. Massaging the injection site (Choice C) can lead to tissue damage and bruising. Inserting the needle at a 10-degree angle (Choice D) is not the correct technique for administering enoxaparin.

Correct Answer: C

Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals to improve absorption and reduce gastrointestinal upset. Metformin is typically recommended to be taken with food to minimize side effects. Option A is incorrect as taking metformin on an empty stomach may increase the risk of gastrointestinal side effects. Option B is unrelated as metformin does not interact with potassium-rich foods. Option D is also incorrect as metformin does not cause drowsiness, so there is no need to take it before bed.
