Correct Answer: A

Rationale: The correct instruction for a client with GERD is to avoid eating spicy foods. Spicy foods can trigger GERD symptoms by irritating the esophagus and increasing acid reflux. Choices B, C, and D are incorrect. Eating three large meals each day can exacerbate GERD symptoms by putting pressure on the lower esophageal sphincter, lying down after meals can worsen reflux due to gravity, and increasing dairy product intake may lead to higher fat consumption, which can also trigger GERD symptoms.

Correct Answer: C

Rationale: The correct answer is C: White bread. White bread is low in potassium, making it a suitable choice for clients with chronic kidney disease to prevent hyperkalemia. Canned soup (choice A), bananas (choice B), and processed meats (choice D) are high in potassium and should be limited or avoided by individuals with chronic kidney disease to manage their condition effectively.

Correct Answer: A

Rationale: In a client with a sodium level of 125 mEq/L (hyponatremia), the nurse should administer 0.9% sodium chloride IV to help increase sodium levels. Choice B, administering a hypotonic IV solution, would further decrease the sodium level. Choice C, encouraging oral fluid intake, is contraindicated as it can dilute the sodium concentration further. Choice D, restricting oral fluid intake, could worsen the client's condition by leading to dehydration and further electrolyte imbalances.

Correct Answer: B

Rationale: The correct answer is B: Administer sodium polystyrene sulfonate. Sodium polystyrene sulfonate is used to treat hyperkalemia by promoting the excretion of potassium. Choice A, administering sodium bicarbonate, is incorrect as it is not used to treat hyperkalemia. Choice C, administering calcium gluconate, is incorrect as it is used to treat hypocalcemia, not hyperkalemia. Choice D, administering calcium carbonate, is incorrect as it is used to treat conditions like osteoporosis and indigestion, not hyperkalemia.

Correct Answer: C

Rationale: The correct answer is C: 'Hypokalemia.' Furosemide is a loop diuretic that can lead to potassium depletion (hypokalemia) due to increased urinary excretion of potassium. This can result in adverse effects such as muscle weakness, cardiac dysrhythmias, and other complications. Hyperkalemia (choice A) is not an adverse effect of furosemide but rather an elevated potassium level. Hyperglycemia (choice B) and hyponatremia (choice D) are not typically associated with furosemide use. Therefore, monitoring potassium levels and addressing hypokalemia is crucial in clients taking furosemide.
