Question 1 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 2 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
The following drugs are contraindicated in asthma:
Correct Answer: B
Rationale: Propranolol, a nonselective beta-blocker, can exacerbate asthma symptoms by causing bronchoconstriction.
Question 4 of 5
Which of the following is the only medication that is approved for the management of amyotrophic lateral sclerosis?
Correct Answer: D
Rationale: Riluzole is the only FDA-approved drug for ALS, extending survival by inhibiting glutamate release, reducing excitotoxicity that accelerates motor neuron death. It modestly slows progression, offering a disease-modifying effect. Pramipexole and selegiline, dopamine-related drugs, treat Parkinson's, not ALS. Galantamine, a cholinesterase inhibitor, targets Alzheimer's cognition. Glatiramer manages MS via immune modulation. Riluzole's glutamate antagonism addresses ALS's neurodegenerative mechanism, backed by clinical trials, making it uniquely approved for this fatal condition.
Question 5 of 5
A patient about to receive a morning dose of digoxin has an apical pulse of 53 beats/min. What will the nurse do next?
Correct Answer: D
Rationale: The correct action is to check the radial pulse for 1 full minute. When administering digoxin, it is important to assess the apical pulse before giving the medication. A heart rate of 53 beats/min is below the normal range, especially for a patient taking digoxin, which can slow heart rate further. The nurse should check the radial pulse for a full minute to verify the heart rate accurately and assess for any abnormalities. This step is crucial to ensure patient safety and prevent potential complications associated with bradycardia. In this situation, it is necessary to withhold the dose and notify the prescriber to determine the appropriate course of action based on the assessment findings.
