1. What is the antidote for Heparin?

A. Protamine sulfate
B. Narcan
C. Romazicon
D. Naloxone

Correct answer: A

Rationale: The correct answer is A: Protamine sulfate. Heparin is an anticoagulant medication used to prevent blood clots. In cases of overdose or excessive bleeding due to Heparin, protamine sulfate is administered as the specific antidote. Protamine sulfate works by neutralizing Heparin's anticoagulant activity. Choices B, C, and D are incorrect. Narcan (Naloxone) is used to reverse opioid overdose, Romazicon (Flumazenil) is used to reverse benzodiazepine overdose, and Naloxone is also used to reverse opioid overdose but is not the antidote for Heparin.

2. A healthcare professional is monitoring a client who is receiving spironolactone. Which of the following findings should the professional report to the provider?

A. Serum Sodium 144 mEq/L
B. Urine output 120 mL in 4 hours
C. Serum Potassium 5.2 mEq/L
D. Blood Pressure 140/90 mm Hg

Correct answer: C

Rationale: A serum potassium level of 5.2 mEq/L indicates hyperkalemia, which is a potentially dangerous condition. Spironolactone, a potassium-sparing diuretic, can cause potassium retention, leading to hyperkalemia. This electrolyte imbalance can result in serious consequences such as cardiac dysrhythmias. The healthcare professional should promptly report this finding to the provider, withhold the medication, and take appropriate actions to prevent complications. Monitoring and managing potassium levels are crucial in clients receiving spironolactone. The other options do not directly relate to the potential adverse effects of spironolactone and are within normal limits, making them less urgent to report.

3. A healthcare provider is preparing to administer metoprolol to a client. Which of the following findings should the provider identify as a contraindication to receiving this medication?

A. Bradycardia
B. Hypertension
C. Fever
D. Rash

Correct answer: A

Rationale: Metoprolol, a beta-blocker, is contraindicated in clients with bradycardia as it can further lower the heart rate, potentially leading to more serious complications. Bradycardia is defined as a heart rate below 60 beats per minute, and administering metoprolol in such cases can exacerbate this condition, causing adverse effects on cardiac output. Hypertension, fever, and rash are not contraindications for metoprolol administration.

4. A client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following dietary instructions should the nurse include?

A. Increase your intake of leafy green vegetables.
B. Avoid foods high in vitamin K.
C. Increase your intake of dairy products.
D. Avoid foods high in iron.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can interfere with the effectiveness of Warfarin, an anticoagulant medication. Foods high in vitamin K, such as leafy green vegetables, can reduce the medication's anticoagulant effect. Therefore, clients taking Warfarin should be advised to avoid or consume a consistent amount of foods high in vitamin K to maintain the medication's effectiveness. Choices A, C, and D are incorrect because increasing leafy green vegetables, dairy products, or avoiding foods high in iron are not directly related to the interaction with Warfarin.

5. Medications classified as angiotensin II receptor agents typically end in?

A. Sartan
B. Ase
C. Olol
D. Pril

Correct answer: A

Rationale: Angiotensin II receptor agents belong to the drug class called angiotensin II receptor blockers (ARBs). The generic names of ARBs usually end in -sartan, helping to identify this specific class of medications. Therefore, medications that end in -sartan are likely to be angiotensin II receptor agents. Choices B, C, and D are incorrect because drugs ending in -ase (like streptokinase), -olol (like propranolol), and -pril (like lisinopril) typically belong to different drug classes with distinct mechanisms of action.
