Question 1 of 5
A nurse is caring for a client who started haloperidol five days ago and is experiencing neuroleptic malignant syndrome. Which of the following prescriptions should the nurse anticipate administering?
Correct Answer: C
Rationale:
Rationale: The correct answer is C: Bromocriptine. Bromocriptine is a dopamine agonist that can help in the treatment of neuroleptic malignant syndrome (NMS) by reducing dopamine levels in the brain. NMS is characterized by hyperthermia, muscle rigidity, altered mental status, and autonomic dysfunction. Bromocriptine helps counteract the excessive dopamine levels that contribute to NMS symptoms.
Summary of other choices:
A: Benztropine is an anticholinergic medication used to treat extrapyramidal symptoms but not NMS.
B: Naloxone is an opioid receptor antagonist used to reverse opioid overdose, not indicated for NMS.
D: Diphenhydramine is an antihistamine used for allergic reactions and sedation, not for NMS treatment.
Question 2 of 5
A nurse is preparing to administer the varicella vaccine to a group of clients. The nurse should identify which of the following clients as having a contraindication for receiving this immunization?
Correct Answer: D
Rationale: The correct answer is D: A client who has AIDS. Clients with AIDS have compromised immune systems, making them more vulnerable to potential complications from live vaccines like the varicella vaccine. The live varicella vaccine could lead to serious infections in individuals with weakened immune systems.
Incorrect
Choices:
A: An older adult client living in a long-term care facility - Advanced age alone is not a contraindication for varicella vaccine.
B: A young adult who has an allergy to eggs - The varicella vaccine is not contraindicated in individuals with egg allergies.
C: A child who recently received the human papillomavirus vaccine - There is no contraindication for receiving the varicella vaccine after the HPV vaccine.

Choice
B), Valerian (
Choice

Question 5 of 5
A nurse is caring for a client who has a prescription for nifedipine. Which of the following findings should the nurse assess prior to administration of the medication?
Correct Answer: A
Rationale: The correct answer is A: Blood pressure. Nifedipine is a calcium channel blocker used to treat hypertension. Before administering, the nurse should assess the client's blood pressure as this medication can cause hypotension as a side effect. Monitoring blood pressure ensures safety and effectiveness of the medication. Assessing respiratory rate, temperature, and oxygen saturation are important but not specific to nifedipine administration. Blood pressure is the priority assessment in this case.
