1. A healthcare professional is preparing to administer an intramuscular dose of penicillin to a client with a history of anaphylactic reactions to penicillin. Which action should the healthcare professional take first?
- A. Check the medication order for accuracy.
- B. Have an epinephrine injection available.
- C. Administer a test dose to check for a reaction.
- D. Ask the client about any allergies.
Correct answer: B
Rationale: When dealing with a client who has a history of anaphylactic reactions to penicillin, the priority action for the healthcare professional is to have an epinephrine injection readily available in case of a severe allergic reaction. In such cases, the immediate focus is on being prepared to manage a potentially life-threatening situation. While checking the medication order for accuracy, administering a test dose, and asking the client about allergies are essential steps in medication administration, the first priority is ensuring the availability of epinephrine to address a severe allergic reaction promptly.
2. A client is receiving intravenous gentamicin (Garamycin). Which of the following findings should prompt the nurse to notify the healthcare provider immediately?
- A. Nausea
- B. Hearing loss
- C. Headache
- D. Diarrhea
Correct answer: B
Rationale: Gentamicin (Garamycin) is an aminoglycoside antibiotic known to cause ototoxicity, which can manifest as hearing loss. Hearing loss is a serious adverse effect that should be reported promptly to the healthcare provider to prevent further complications or adjust the treatment regimen. Nausea, headache, and diarrhea are common side effects of gentamicin but are not as severe or urgent as hearing loss in this context.
3. The client with small cell lung cancer is being treated with etoposide (VePesid). The nurse assisting in caring for the client during its administration understands that which side effect is specifically associated with this medication?
- A. Alopecia
- B. Chest pain
- C. Pulmonary fibrosis
- D. Orthostatic hypotension
Correct answer: D
Rationale: The correct answer is 'D: Orthostatic hypotension.' Etoposide is associated with orthostatic hypotension, a sudden drop in blood pressure that can occur when transitioning from lying down to standing up. It is important for the nurse to monitor the client's blood pressure during the infusion to detect and manage this potential side effect.
4. Desmopressin acetate (DDAVP) is prescribed for the treatment of diabetes insipidus. The nurse monitors the client after medication administration for which therapeutic response?
- A. Decreased urinary output
- B. Decreased blood pressure
- C. Decreased peripheral edema
- D. Decreased blood glucose level
Correct answer: A
Rationale: Desmopressin promotes renal conservation of water by increasing the permeability of kidney collecting ducts to water, resulting in decreased urinary output. Therefore, the therapeutic response expected after administering desmopressin for diabetes insipidus is a reduction in urinary output.
5. A postoperative client has received a dose of naloxone hydrochloride for respiratory depression shortly after transfer to the nursing unit from the postanesthesia care unit. After administration of the medication, the nurse checks the client for:
- A. Pupillary changes
- B. Scattered lung wheezes
- C. Sudden increase in pain
- D. Sudden episodes of diarrhea
Correct answer: C
Rationale: Naloxone hydrochloride is an antidote to opioids and may be administered to postoperative clients to address respiratory depression. This medication can also reverse the effects of analgesics, potentially leading to a sudden increase in pain. Therefore, the nurse must assess the client for any unexpected rise in pain levels after naloxone administration. Choices A, B, and D are incorrect because pupillary changes, scattered lung wheezes, and sudden episodes of diarrhea are not typically associated with naloxone administration for respiratory depression.
