Extract:
Question 1 of 5
A nurse is reinforcing teaching with a newly licensed nurse about monitoring morphine patient-controlled analgesia (PCA). Which of the following information should the nurse include?
Correct Answer: A
Rationale: Only the client should operate the PCA pump to ensure self-administration within prescribed limits. Pain assessment should be more frequent, and the client's pain level should be assessed as needed, not on a fixed schedule. Morphine PCA allows the client to self-administer a predetermined dose, minimizing the risk of overdose or toxicity. Constipation, not diarrhea, is a common adverse effect of opioid medications, including morphine.
Question 2 of 5
A nurse is reinforcing teaching with a client who has chronic stable angina and a new prescription for sublingual nitroglycerin. Which of the following instructions should the nurse include in the teaching?
Correct Answer: D
Rationale: Nitroglycerin is meant to be absorbed under the tongue, and water is not necessary. The client should take up to three doses 5 minutes apart and seek emergency medical attention if pain persists. The maximum number of tablets that should be taken in 15 minutes is 3 and not 4 since this could cause severe hypotension and headache. Nitroglycerin tablets are meant to be dissolved under the tongue, not chewed or swallowed. Sublingual nitroglycerin is used to prevent angina attacks by dilating the coronary arteries and increasing blood flow to the heart. The client should take one tablet for 5 to 10 minutes before engaging in an activity that might trigger angina, such as exercise, stress, or cold exposure.
Question 3 of 5
A nurse is monitoring a client who received naloxone to counteract the effects of an opioid overdose. Which of the following findings should indicate to the nurse that the medication is effective?
Correct Answer: C
Rationale: Naloxone administration may lead to an increase in blood pressure, not a decrease. While pain relief might occur, the primary goal of naloxone is to reverse respiratory depression, not to relieve pain. Naloxone is an opioid antagonist that reverses opioid-induced respiratory depression, so an increased respiratory rate indicates its effectiveness. Naloxone does not typically affect body temperature in a significant way.
Question 4 of 5
A nurse is caring for a client who has been taking epoetin alfa for 3 months. Which of the following laboratory tests should the nurse monitor to determine the effectiveness of the medication?
Correct Answer: C
Rationale: T4 is a thyroid hormone, and monitoring it is not relevant for assessing the effectiveness of epoetin alfa. Troponin is a marker for cardiac injury and is not relevant for assessing the effectiveness of epoetin alfa. Epoetin alfa stimulates the production of red blood cells, so monitoring hemoglobin levels is crucial to assess its effectiveness. AST is a liver enzyme and is not relevant for assessing the effectiveness of epoetin alfa.
Question 5 of 5
A nurse is collecting data from a client following his first dose of captopril. The client's blood pressure is 88/60 mm Hg. Which of the following actions should the nurse take first?
Correct Answer: A
Rationale: The first action is to place the client in a supine position. The client might experience a first-dose phenomenon, which is a sudden and severe drop in blood pressure within 1 to 3 hours of taking the medication. The nurse should place the client in a supine position to prevent orthostatic hypotension and syncope. This should be done after placing the client in a supine position to assess for postural changes. This should be done after placing the client in a supine position to assess for postural changes. The nurse should not administer a saline bolus unless prescribed by the provider, as this could cause fluid overload and worsen heart failure.
