Question 1 of 5
A nurse is caring for a client who received a dose of IV morphine for pain. Which of the following vital signs indicates the client is having an adverse reaction to the medication?
Correct Answer: D
Rationale: The correct answer is D: Respiratory rate 10/min. A decreased respiratory rate is indicative of respiratory depression, a serious adverse reaction to morphine. Morphine is a central nervous system depressant that can slow down the respiratory drive, leading to hypoventilation and potentially respiratory arrest. In contrast, choices A, B, and C are within normal limits and not specific to morphine adverse effects. A high blood pressure may be seen with pain or anxiety, while a normal temperature and heart rate are not typically affected by morphine.
Therefore, the respiratory rate is the most critical vital sign to monitor for adverse reactions to IV morphine.
Question 2 of 5
A nurse is reviewing the list of current medications for a client who has a new prescription for nitroglycerin. The nurse should identify that which of the following client medications is contraindicated for use with nitroglycerin?
Correct Answer: A
Rationale: The correct answer is A: Sildenafil. Nitroglycerin and sildenafil both cause vasodilation and together can lead to severe hypotension. Sildenafil is a phosphodiesterase type 5 inhibitor used for erectile dysfunction. Gemfibrozil is a lipid-lowering agent, Lansoprazole is a proton pump inhibitor, and Diazepam is a benzodiazepine, none of which have significant interactions with nitroglycerin.
Question 3 of 5
A nurse is assessing a client who has septic shock and is receiving dopamine by continuous IV infusion. Which of the following findings indicates that the nurse should increase the rate of infusion?
Correct Answer: B
Rationale: The correct answer is B: Hypotension. In septic shock, hypotension is a common sign of inadequate tissue perfusion. Dopamine is a vasopressor that helps increase blood pressure by constricting blood vessels.
Therefore, if the client is still hypotensive despite receiving dopamine, it indicates that the current infusion rate is not sufficient to maintain adequate perfusion. Increasing the infusion rate can help improve blood pressure and perfusion.
Incorrect choices:
A: Headache - Not a direct indication of dopamine infusion rate adjustment.
C: Chest pain - Not a direct indication of dopamine infusion rate adjustment.
D: Extravasation - Indicates leakage of medication from the IV site, not a need to adjust infusion rate.
Question 4 of 5
A nurse is caring for a client in the post-anesthesia unit who is experiencing malignant hyperthermia. Which of the following prescriptions should the nurse anticipate administering?
Correct Answer: D
Rationale: The correct answer is D: Dantrolene. Dantrolene is the drug of choice for treating malignant hyperthermia, a rare but life-threatening condition triggered by certain medications used during anesthesia. Dantrolene works by inhibiting the release of calcium from the sarcoplasmic reticulum in skeletal muscle cells, which helps to reduce muscle contractions and hyperthermia. Verapamil (
A) is a calcium channel blocker used for different purposes. Naloxone (
B) is an opioid antagonist used for opioid overdoses. Cefazolin (
C) is an antibiotic used for treating infections. In summary, Dantrolene is the appropriate choice for managing malignant hyperthermia due to its mechanism of action in preventing further muscle contraction and hyperthermia.
Question 5 of 5
A nurse is caring for a client who is taking warfarin and reports taking several new herbal supplements. The nurse should identify which of the following supplements is contraindicated for concurrent use with warfarin?
Correct Answer: A
Rationale: The correct answer is A: Ginkgo biloba. Ginkgo biloba can increase the risk of bleeding when taken with warfarin due to its anticoagulant properties, potentially leading to serious complications. Coenzyme Q10 (
Choice
B), Valerian (
Choice
C), and Probiotics (
Choice
D) do not have significant interactions with warfarin. Ginkgo biloba is the only supplement in the list known to interact adversely with warfarin.
