1. 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.
2. When a nurse assesses a client's IV catheter insertion site and notes a hematoma, which of the following actions should the nurse take? (Select all that apply.)
- A. Stop the infusion.
- B. Apply alcohol to the insertion site.
- C. Apply warm compresses to the insertion site.
- D. Elevate the client's arm.
Correct answer: C
Rationale: When a nurse detects a hematoma at the IV catheter insertion site, applying warm compresses is beneficial as it can promote healing by enhancing circulation and reducing swelling. Elevating the client's arm helps in reducing edema, which can relieve pressure, pain, and further bleeding in the hematoma area. Stopping the infusion may be necessary in certain situations, but it is not a standard action for all hematoma cases. Applying alcohol to the insertion site is discouraged as it can cause irritation and may not aid in resolving the hematoma.
3. A client has a new prescription for Morphine to manage post-operative pain. Which of the following assessments should the nurse perform first?
- A. Urine output
- B. Bowel sounds
- C. Pain level
- D. Respiratory rate
Correct answer: D
Rationale: The nurse should prioritize assessing the client's respiratory rate first when administering Morphine due to the risk of respiratory depression, which is a life-threatening adverse effect of this medication. Monitoring the respiratory rate is crucial to detect any signs of respiratory distress early and take prompt action to ensure the client's safety. Assessing urine output, bowel sounds, and pain level are also important but not as critical as monitoring respiratory rate when initiating Morphine therapy.
4. What is levothyroxine's pharmacologic classification?
- A. Thyroid Preparations
- B. Metabolic Inhibitors
- C. Analgesic
- D. Loop Diuretic
Correct answer: A
Rationale: Levothyroxine is classified as a thyroid preparation because it is a synthetic form of the thyroid hormone thyroxine. It is primarily used to treat hypothyroidism by supplementing or replacing the natural thyroid hormones in the body, helping to regulate metabolism and energy levels. Choice B, Metabolic Inhibitors, is incorrect because levothyroxine does not inhibit metabolism but rather helps regulate it. Choice C, Analgesic, is incorrect as levothyroxine is not used for pain relief but for thyroid hormone replacement therapy. Choice D, Loop Diuretic, is also incorrect as loop diuretics are medications that act on the kidneys to increase urine production and are not related to thyroid hormone replacement therapy.
5. A healthcare provider is providing discharge instructions to a client who is prescribed Warfarin. Which of the following dietary instructions should the provider 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 to avoid foods high in vitamin K. Vitamin K can interfere with the effectiveness of Warfarin by counteracting its anticoagulant effects. Foods high in vitamin K, such as leafy green vegetables, should be limited in the diet of individuals taking Warfarin to maintain a consistent level of the medication's effectiveness. Choices A, C, and D are incorrect as increasing intake of leafy green vegetables (choice A) and dairy products (choice C) may increase the intake of vitamin K, which is not recommended, and avoiding foods high in iron (choice D) is not directly related to Warfarin therapy.
