1. A client has been prescribed Phenelzine for depression. Which of the following indicates that the client has developed an adverse effect of this medication?
- A. Orthostatic hypotension
- B. Hearing loss
- C. Gastrointestinal bleeding
- D. Weight loss
Correct answer: A
Rationale: Orthostatic hypotension is a known adverse effect of Phenelzine, a monoamine oxidase inhibitor (MAOI) used for depression. It is caused by a sudden drop in blood pressure when changing positions, leading to symptoms like dizziness or fainting. Monitoring for orthostatic hypotension is crucial during Phenelzine therapy to prevent complications. Choices B, C, and D are incorrect because hearing loss, gastrointestinal bleeding, and weight loss are not typically associated with Phenelzine use.
2. Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?
- A. Heparin
- B. Alprazolam
- C. Digoxin
- D. Levothyroxine
Correct answer: C
Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.
3. When educating a client who has a prescription for Propranolol, what instruction should the healthcare provider include?
- A. Take this medication with food.
- B. Discontinue the medication if you feel fatigued.
- C. Expect to have decreased heart rate with this medication.
- D. Do not stop taking this medication abruptly.
Correct answer: D
Rationale: The correct instruction for a client with a prescription for Propranolol is not to stop taking the medication abruptly. Abrupt cessation can result in rebound hypertension or other cardiac complications. It is crucial for the client to taper off the medication gradually under healthcare provider supervision to prevent adverse effects. Choice A is incorrect because Propranolol can be taken with or without food. Choice B is incorrect as discontinuing the medication based on fatigue alone is not advisable without consulting a healthcare provider. Choice C is incorrect because while Propranolol can decrease heart rate, it is not the primary instruction to provide in this scenario.
4. When administering digoxin (Lanoxin) to a patient, the healthcare provider observes various signs and symptoms of an overdose. Which of the following should the healthcare provider give to reverse digoxin toxicity?
- A. Naloxone
- B. Vitamin K
- C. Digibind
- D. Flumazenil
Correct answer: C
Rationale: Digibind, also known as Digoxin immune Fab, is the specific antidote used to treat digoxin toxicity. It works by binding to digoxin in the body, forming a complex that can be excreted by the kidneys, thereby reversing the toxic effects of digoxin overdose. Naloxone is used for opioid overdoses, not digoxin toxicity. Vitamin K is used to reverse the effects of warfarin overdose. Flumazenil is used to reverse the effects of benzodiazepine overdose, not digoxin toxicity.
5. A healthcare provider is completing a client's medical history. The client takes Simvastatin. The healthcare provider should identify which of the following disorders as a contraindication to adding Ezetimibe to the client's medications?
- A. History of severe constipation
- B. History of hypertension
- C. Active hepatitis C
- D. Type 2 diabetes mellitus
Correct answer: C
Rationale: Ezetimibe is contraindicated in patients with active moderate-to-severe liver disorders, such as active hepatitis C, especially when they are already taking a statin like simvastatin. This combination can increase the risk of liver problems and is not recommended due to the potential for further liver damage. Choices A, B, and D are not directly contraindications for adding Ezetimibe to the client's medications.
