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. A child is prescribed Amoxicillin 20 mg/kg/day PO to be administered every 12 hr. The child weighs 44 lb. The available medication is amoxicillin suspension 250 mg/5 mL. How many mL should be given per dose?
- A. 4 mL
- B. 5 mL
- C. 6 mL
- D. 3 mL
Correct answer: A
Rationale: To calculate the dosage per administration: Convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the nurse should administer 4 mL of amoxicillin suspension per dose. Choice B, 5 mL, is incorrect because the calculation shows that 4 mL is the correct dose. Choices C and D are also incorrect as they are not in line with the calculated dosage based on the weight of the child and the concentration of the medication.
3. A client has a new prescription for Losartan. Which of the following instructions should be included?
- A. Avoid drinking grapefruit juice.
- B. Take this medication with a full glass of water.
- C. Take this medication on an empty stomach.
- D. Monitor for signs of dehydration.
Correct answer: D
Rationale: The correct instruction for a client prescribed Losartan is to monitor for signs of dehydration. Losartan can lead to dehydration, so it is essential for the client to be vigilant for symptoms such as dry mouth, increased thirst, and decreased urine output. Providing the instruction to monitor for signs of dehydration ensures the client's safety and helps in early identification of any potential issues related to dehydration. Choices A, B, and C are incorrect as Losartan does not interact with grapefruit juice, does not require specific instructions regarding water intake, and does not need to be taken on an empty stomach.
4. While providing teaching to a client with a new prescription for Enalapril, the nurse should instruct the client to report which of the following manifestations as an adverse effect of this medication?
- A. Tremors
- B. Dry cough
- C. Drowsiness
- D. Hyperactivity
Correct answer: B
Rationale: The correct answer is 'B: Dry cough.' Enalapril is an ACE inhibitor known to cause a persistent dry cough as a common adverse effect. This cough should be reported to the healthcare provider for further evaluation, as it may indicate a potential issue with the medication that needs attention to ensure the client's well-being. Tremors (Choice A), drowsiness (Choice C), and hyperactivity (Choice D) are not typically associated with Enalapril use. Therefore, they are incorrect choices for this question.
5. A client is taking Paroxetine to treat PTSD and reports teeth grinding at night. Which interventions should the nurse implement to manage Bruxism? (Select all that apply.)
- A. Concurrent administration of buspirone.
- B. Administration of a different SSRI.
- C. Use of a mouth guard.
- D. Changing to a different class of antidepressant medication.
Correct answer: A
Rationale: The correct interventions to manage Bruxism associated with Paroxetine use include A: Concurrent administration of buspirone. Buspirone can help alleviate the side effect of Bruxism. Additionally, C: Use of a mouth guard is recommended to prevent oral damage from teeth grinding. B: Administration of a different SSRI is not necessary since the issue is specific to Paroxetine. D: Changing to a different class of antidepressant medication may be considered in severe cases, but the initial step should be to add buspirone to address the Bruxism caused by Paroxetine.
