Question 1 of 5
A nurse is preparing to administer a scheduled dose of warfarin to a client. Which of the following laboratory tests should the nurse review prior to administration?
Correct Answer: A
Rationale: The correct answer is A: PT (Prothrombin Time). Prothrombin Time measures the extrinsic pathway of the coagulation cascade, which is directly affected by warfarin. By reviewing the PT, the nurse can assess the client's clotting time and ensure that the warfarin dose is appropriate.
Total iron-binding capacity (
B) is not relevant to warfarin administration. White blood cell count (
C) assesses immune function, not clotting factors affected by warfarin. Partial Thromboplastin Time (
D) measures the intrinsic pathway of coagulation, not directly affected by warfarin.
Question 2 of 5
A nurse is providing teaching to a client who has a new prescription for carbamazepine for the treatment of seizures. The nurse should instruct the client to monitor for which of the following adverse effects?
Correct Answer: A
Rationale: The correct answer is A: Blurred vision. Carbamazepine is known to cause ocular side effects, including blurred vision. The rationale is that carbamazuepine can lead to changes in the eye's ability to focus, causing blurred vision as a common adverse effect. This is important for the client to monitor because it can impact their daily activities and driving. The other choices, B: Insomnia, C: Metallic taste, and D: Tachypnea, are not typically associated with carbamazepine use. Insomnia is more commonly seen with stimulant medications, metallic taste is associated with certain antibiotics, and tachypnea is not a common side effect of carbamazepine.
Therefore, the correct answer is A because it directly relates to the medication's known adverse effects.
Question 3 of 5
A nurse is preparing to administer filgrastim 5 mcg/kg/day subcutaneous to a client who weighs 143 lb. How many mcg should the nurse administer per day? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the dose of filgrastim for the client, first convert the weight from pounds to kilograms. 143 lb / 2.2 = 65 kg.
Then, multiply the weight in kg by the dosage of 5 mcg/kg/day. 65 kg * 5 mcg/kg/day = 325 mcg/day.
Therefore, the correct answer is A: 325 mcg/day.
Choices B, C, and D are incorrect because they do not accurately calculate the dose based on the client's weight and the prescribed dosage.
Question 4 of 5
A nurse is assessing a client who has heart failure and is taking furosemide. Which of the following findings should indicate to the nurse that the client is experiencing fluid volume deficit?
Correct Answer: D
Rationale: The correct answer is D: Elevated hematocrit level. In fluid volume deficit, there is a decrease in fluid volume in the body leading to increased concentration of red blood cells, resulting in an elevated hematocrit level. This occurs because the body is trying to compensate for the decreased fluid volume by increasing the concentration of red blood cells in the blood.
Weight gain (
A) is a sign of fluid volume excess, not deficit. Distended neck veins (
B) are a sign of fluid volume overload, typically seen in heart failure. Shortness of breath (
C) is a common symptom of heart failure but not specific to fluid volume deficit.
Question 5 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.
