Question 1 of 5
The patient has a potassium level of 5.9 mEq/L. The nurse is administering glucose and insulin. The patient's wife says, 'He doesn't have diabetes, why is he getting insulin?' What is the best response by the nurse?
Correct Answer: A
Rationale: In hyperkalemia (5.9 mEq/L), insulin shifts potassium into cells , lowering serum levels temporarily, paired with glucose to avoid hypoglycemia. Choice B misstates excretion. Choice C compares unnecessarily. Choice D attributes renal action incorrectly. A explains the mechanism accurately, making it the best response.

Question 3 of 5
Which of the following is the antidote for Heparin?
Correct Answer: A
Rationale: Protamine sulfate is the antidote for Heparin. Heparin is an anticoagulant medication that works by inhibiting the clotting factors in the blood. In cases of Heparin overdose or when there is a need to reverse its anticoagulant effects quickly, protamine sulfate can be administered. Protamine sulfate binds to Heparin and neutralizes its anticoagulant effects, making it an effective antidote. It is important to administer the antidote under the guidance of a healthcare professional to prevent any adverse reactions.
Question 4 of 5
A patient with a history of pancreatitis and cirrhosis is also being treated for hypertension. Which drug will most likely be ordered for this patient?
Correct Answer: C
Rationale: In a patient with a history of pancreatitis and cirrhosis, medications that may exacerbate pancreatic or hepatic issues should be avoided. Among the choices provided, diltiazem is the most suitable antihypertensive medication for this patient. Diltiazem is a calcium channel blocker that does not rely on hepatic metabolism for its action, making it a safe choice for patients with liver disease. In addition, it does not have a significant effect on pancreatic function, making it a preferred option in a patient with pancreatitis. Therefore, diltiazem is the most appropriate choice for this patient with a history of pancreatitis and cirrhosis who requires treatment for hypertension.
Question 5 of 5
The nurse is preparing to give a potassium supplement. Which laboratory test should be checked before the patient receives a dose of potassium?
Correct Answer: B
Rationale: Before administering potassium supplements to a patient, it is essential to check the patient's serum potassium level. This allows the healthcare provider to assess the current potassium level in the body and determine if supplementation is necessary. Monitoring serum potassium levels is crucial because both low potassium (hypokalemia) and high potassium (hyperkalemia) levels can have serious health implications. Administering potassium supplements without checking the serum potassium level could lead to adverse effects or complications, so it is important to confirm the need for supplementation based on this laboratory test.
