Correct Answer: B

Rationale: Assisting the client to splint the incision with a pillow while coughing is the correct action in this scenario. This intervention helps reduce pain and prevent wound dehiscence, which is the partial or complete separation of the layers of a surgical wound. Monitoring urinary output is important but not the priority at this immediate postoperative stage. Providing a clear liquid diet may be indicated later but is not the most immediate concern. Encouraging ambulation is beneficial for preventing complications like deep vein thrombosis, but splinting the incision is more crucial at this early postoperative period.

Correct Answer: A

Rationale: Observing facial expressions is essential in assessing pain levels in non-verbal patients. Non-verbal cues, such as facial grimacing, furrowed brows, or clenched jaws, can provide valuable information about the patient's pain experience. Using the Wong-Baker faces scale or assessing heart rate may not be as effective in non-verbal patients as they are unable to communicate their pain through these methods. Asking the patient to rate their pain is also not suitable for non-verbal patients as they may not have the ability to verbally communicate their pain levels.

Correct Answer: D

Rationale: The correct answer is D, 'Take with a glass of orange juice.' Ferrous sulfate is best absorbed with vitamin C, making orange juice the preferred choice. Choices A, B, and C are incorrect because taking ferrous sulfate with meals, at bedtime, or with milk can reduce its absorption due to interactions with food components like calcium, inhibiting the iron absorption process.

Correct Answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

Correct Answer: B

Rationale: The correct answer is B: Mouth sores. Mouth sores are a common side effect of radiation therapy, especially when the treatment is focused on the head or neck area. Weight gain is not typically associated with radiation therapy; instead, clients may experience weight loss due to side effects like nausea and loss of appetite. Hyperpigmentation is not a common finding related to radiation therapy. Increased saliva production is not a typical side effect of radiation therapy; instead, clients may experience dry mouth.
