Question 1 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 2 of 5
A nurse is caring for a client who has received propofol during a colonoscopy. The nurse should monitor for which of the following as an adverse effect of the medication?
Correct Answer: B
Rationale: The correct answer is B: Decrease in respiratory rate. Propofol is a sedative-hypnotic medication that can cause respiratory depression as a common adverse effect. This is due to its central nervous system depressant effects. The nurse should monitor the client closely for signs of decreased respiratory rate, such as shallow breathing or respiratory distress. Monitoring respiratory status is crucial to prevent respiratory compromise or arrest.
Other choices are incorrect:
A: Increase in heart rate - Propofol typically causes a decrease in heart rate, not an increase.
C: Increase in bowel function - Propofol does not affect bowel function.
D: Decrease in body temperature - Propofol is not known to cause a decrease in body temperature.
Question 3 of 5
A nurse is taking a medication history from a client who has a new prescription for levothyroxine. The nurse should instruct the client to wait 4 hr after taking levothyroxine before taking which of the following supplements?
Correct Answer: B
Rationale: The correct answer is B: Calcium. Levothyroxine should be taken on an empty stomach to ensure optimal absorption. Calcium can interfere with the absorption of levothyroxine, so it is recommended to wait at least 4 hours after taking levothyroxine before consuming calcium supplements. Ginkgo biloba, Vitamin C, and Zinc do not significantly interfere with levothyroxine absorption, so there is no need to wait specifically for them. Calcium is the correct choice because of its known interference with levothyroxine absorption.
Question 4 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.
Question 5 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.
