1. A 6-month-old infant is prescribed digoxin for the treatment of congestive heart failure. Which observation by the practical nurse (PN) warrants immediate intervention for signs of digoxin toxicity?
- A. Apical heart rate of 60 beats/min
- B. Sweating across the forehead
- C. Poor sucking effort
- D. Respiratory rate of 30 breaths/min
Correct answer: A
Rationale: A heart rate of 60 beats/min for a 6-month-old infant warrants immediate intervention as it falls below the normal range. The normal heart rate for a 6-month-old is 80 to 150 beats/min when awake, and a rate of 70 beats/min while sleeping is considered within normal limits. Bradycardia (heart rate <60 beats/min) in infants can be a sign of digoxin toxicity, necessitating prompt evaluation and intervention to prevent adverse effects. Sweating across the forehead (Choice B) is a non-specific symptom and may not directly indicate digoxin toxicity. Poor sucking effort (Choice C) and a respiratory rate of 30 breaths/min (Choice D) are not typically associated with digoxin toxicity and do not require immediate intervention in the context of this question.
2. A client is prescribed an antacid for the treatment of peptic ulcer disease. What is the action of this medication that is effective in treating the client's ulcer?
- A. Decrease in the production of gastric secretions
- B. Production of an adherent barrier over the ulcer
- C. Maintenance of a gastric pH of 3.5 or above
- D. Decrease in the gastric motor activity
Correct answer: C
Rationale: The correct answer is C. Antacids work by neutralizing gastric acids and maintaining a gastric pH of 3.5 or above. This pH level is crucial to prevent the activation of pepsinogen, a precursor to pepsin, which can further damage the ulcer. Choice A is incorrect because antacids do not directly decrease the production of gastric secretions; they neutralize existing acid. Choice B is incorrect as antacids do not form a physical barrier over the ulcer but rather neutralize the acid around it. Choice D is also incorrect as antacids do not affect gastric motor activity but focus on reducing acidity in the stomach.
3. A postoperative client has a prescription for ketorolac 30mg IV q6h. Which response demonstrates that therapeutic levels of the medication have been achieved?
- A. Observe wound drainage for a change in appearance
- B. Assess the client's calves for inflammation
- C. Perform a pain assessment using a numeric scale
- D. Measure the client's intake and output
Correct answer: C
Rationale: The correct response is to perform a pain assessment using a numeric scale. Ketorolac is an NSAID prescribed for pain relief. Monitoring pain levels is crucial to evaluate the therapeutic effectiveness of the medication. Pain assessment helps determine if the medication is providing adequate pain relief, indicating that therapeutic levels have been achieved.
4. A client with diabetes mellitus type 2 is prescribed glipizide. What instruction should the nurse include in the client's teaching plan?
- A. Take this medication with meals.
- B. Avoid alcohol while taking this medication.
- C. Take this medication on an empty stomach.
- D. Report any signs of hypoglycemia to the healthcare provider.
Correct answer: A
Rationale: The correct instruction for a client prescribed glipizide, a sulfonylurea used to lower blood sugar levels, is to take the medication with meals. Taking it with meals helps to minimize the risk of hypoglycemia by ensuring a more balanced effect on blood glucose levels throughout the day. It is important for the client to follow this instruction to maintain stable blood sugar levels and reduce the likelihood of experiencing low blood sugar (hypoglycemia) episodes. Choice B is incorrect because there are no specific contraindications between glipizide and alcohol. Choice C is incorrect as glipizide should not be taken on an empty stomach. Choice D is incorrect as while it is important to report signs of hypoglycemia, the primary focus should be on preventing hypoglycemia by taking the medication with meals.
5. A client who is recovering from an appendectomy is receiving narcotics. Earlier, the nurse witnessed the client's family pushing the pain pump. What should the nurse implement?
- A. Check the client's level of consciousness
- B. Instruct the family not to push the button
- C. Stop the client's basal infusion
- D. Administer a narcotic reversal medication
Correct answer: B
Rationale: Instructing the family not to push the button is necessary to prevent the client from receiving an excessive amount of narcotics, ensuring the safe and appropriate use of the pain pump. Checking the client's level of consciousness may not address the issue of family members pushing the button. Stopping the client's basal infusion is not indicated unless there are specific medical reasons for doing so. Administering a narcotic reversal medication is not necessary at this point as the issue lies with inappropriate use rather than an overdose.
