Correct Answer: A

Rationale: Corrected Rationale: Bradypnea, or slow breathing, is a common sign of opioid toxicity. When a client is experiencing opioid toxicity, the respiratory system is usually the most affected, leading to a decrease in the respiratory rate (bradypnea). Tachycardia (increased heart rate), hypertension (high blood pressure), and diaphoresis (excessive sweating) are not typical manifestations of opioid toxicity. Therefore, the correct answer is bradypnea.

Correct Answer: A

Rationale: Corrected Rationale: The correct answer is A, left upper quadrant pain. In acute pancreatitis, inflammation of the pancreas commonly causes pain in the left upper quadrant of the abdomen. This pain can be severe and radiate to the back. Periumbilical pain (choice B) is more indicative of acute appendicitis. Rebound tenderness (choice C) is associated with peritoneal inflammation, not specifically pancreatitis. Flank pain (choice D) is more characteristic of conditions involving the kidneys or ureters, such as renal colic.

Correct Answer: B

Rationale: The correct answer is B: 'Check your pulse before taking this medication.' When a patient is prescribed digoxin, it is crucial to monitor their pulse rate because digoxin can cause bradycardia (slow heart rate) as a side effect. In contrast, choices A, C, and D are incorrect. Taking digoxin with meals is not necessary; it should be taken consistently at the same time every day. Taking digoxin with an antacid is not recommended as it can interfere with the absorption of the medication. While digoxin can cause hypokalemia (low potassium levels), patients should not increase their potassium intake without healthcare provider guidance to avoid potential complications.

Correct Answer: B

Rationale: The correct answer is B: JVD. Jugular venous distention (JVD) is a common finding in right-sided heart failure due to fluid overload. This occurs because the right side of the heart is unable to effectively pump blood, leading to congestion and increased venous pressure, which is manifested as JVD. Choices A, C, and D are incorrect. Peripheral edema (choice A) is more commonly associated with left-sided heart failure. Crackles in the lungs (choice C) are indicative of pulmonary edema, often seen in left-sided heart failure. Hypotension (choice D) is not typically seen in right-sided heart failure, as it is more commonly associated with conditions like shock or severe dehydration.

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.
