Correct Answer: B

Rationale: The correct answer is to instruct the client to avoid lifting heavy objects for at least 6 weeks after a mastectomy. This is important to prevent complications and promote proper healing. Choice A is incorrect because tight-fitting bras can increase the risk of lymphedema and discomfort. Choice C is incorrect as sleeping on the affected side can cause discomfort and interfere with healing. Choice D is incorrect as initiating arm exercises too soon after surgery can strain the surgical site and hinder recovery.

Correct Answer: A

Rationale: The correct answer is to assess the patient for injuries. When a patient experiences a fall in the hospital, the immediate concern is to check for any injuries that may require urgent care. Calling for help can be done after assessing the patient to ensure appropriate assistance is provided. Documenting the fall is important for the patient's medical record, but it is not the most immediate action needed. Notifying the healthcare provider can come after the initial assessment to update them on the situation.

Correct Answer: C

Rationale: The correct instruction for a client taking furosemide is to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss, so increasing potassium-rich foods helps prevent hypokalemia. Choice A, avoiding prolonged exposure to sunlight, is not directly related to furosemide use. Choice B, taking the medication with a meal, is not a specific requirement for furosemide administration. Choice D, limiting fluid intake to 1 liter per day, is not the correct advice as furosemide is a diuretic that often requires increased fluid intake to prevent dehydration.

Correct Answer: A

Rationale: Monitoring daily weight is the most accurate way to assess fluid overload in patients with heart failure. In heart failure, the body retains excess fluid, leading to weight gain. Monitoring daily weight allows healthcare professionals to track fluid retention accurately. Checking for edema (Choice B) is a valuable assessment technique, but it may not be as sensitive as monitoring daily weight. Monitoring blood pressure (Choice C) is essential in managing heart failure, but it is not the most accurate way to assess fluid overload. Checking oxygen saturation (Choice D) is important to assess respiratory status but is not directly related to fluid overload in heart failure.

Correct Answer: A

Rationale: The correct answer is to administer antihistamines as the initial intervention for a patient experiencing an allergic reaction. Antihistamines work to block the effects of histamine, a substance released during an allergic reaction, helping to relieve symptoms such as itching, swelling, and hives. Corticosteroids (Choice B) are sometimes used in severe cases to reduce inflammation, but they are not the first-line treatment for an allergic reaction. Administering oxygen (Choice C) may be necessary if the patient is having difficulty breathing, but it is not the first intervention. IV fluids (Choice D) are typically given for conditions like dehydration or shock, not as the primary intervention for an allergic reaction.
