1. Which of the following is the best indicator of fluid balance in a patient with heart failure?
- A. Daily weight measurements.
- B. Monitoring intake and output.
- C. Assessing skin turgor.
- D. Checking for peripheral edema.
Correct answer: A
Rationale: Daily weight measurements are the best indicator of fluid balance in a patient with heart failure. Changes in weight reflect fluid retention or loss more accurately than other methods. Monitoring intake and output (choice B) is essential but may not provide a comprehensive picture of fluid status. Skin turgor (choice C) and checking for peripheral edema (choice D) are more indicative of dehydration and fluid overload, respectively, rather than overall fluid balance.
2. Which of the following lipid abnormalities is a risk factor for the development of atherosclerosis and peripheral vascular disease?
- A. Low concentration of triglycerides.
- B. High levels of high-density lipoprotein (HDL) cholesterol.
- C. High levels of low-density lipoprotein (LDL) cholesterol.
- D. Low levels of LDL cholesterol.
Correct answer: C
Rationale: The correct answer is C: High levels of low-density lipoprotein (LDL) cholesterol. High levels of LDL cholesterol contribute to the development of atherosclerosis and peripheral vascular disease by being deposited in the blood vessel walls, leading to the formation of plaques that can obstruct blood flow. Choice A is incorrect as a low concentration of triglycerides is not typically associated with an increased risk of atherosclerosis or PVD. Choice B is incorrect as high levels of high-density lipoprotein (HDL) cholesterol are actually considered protective against atherosclerosis as it helps remove cholesterol from arteries. Choice D is incorrect as low levels of LDL cholesterol are not typically considered a risk factor for atherosclerosis or PVD.
3. In a 46-year-old female client admitted for acute renal failure secondary to diabetes and hypertension, which test is the best indicator of adequate glomerular filtration?
- A. Serum creatinine.
- B. Blood urea nitrogen (BUN).
- C. Sedimentation rate.
- D. Urine specific gravity.
Correct answer: A
Rationale: The correct answer is A: Serum creatinine. Creatinine is a product of muscle metabolism that is filtered by the glomerulus. Blood levels of creatinine are not affected by dietary or fluid intake, making it a reliable indicator of kidney function. An elevated creatinine level strongly suggests nephron loss, indicating decreased glomerular filtration rate. Choice B, Blood Urea Nitrogen (BUN), reflects the amount of urea nitrogen in the blood and can be influenced by factors other than kidney function, such as protein intake and liver health, making it less specific for evaluating glomerular filtration. Choice C, Sedimentation rate, is a measure of how quickly red blood cells settle in a test tube and is not a direct marker of kidney function. Choice D, Urine specific gravity, mainly reflects the kidney's ability to concentrate urine and is not a direct indicator of glomerular filtration rate. Therefore, Serum creatinine is the most appropriate test to assess glomerular filtration in this scenario.
4. Prior to a percutaneous kidney biopsy, which actions should a nurse take? (Select all that apply.)
- A. Keep the client NPO for 4 to 6 hours.
- B. Obtain coagulation study results.
- C. Maintain strict bedrest in a supine position.
- D. A & B
Correct answer: D
Rationale: Prior to a percutaneous kidney biopsy, the nurse should ensure that the client is kept NPO for 4 to 6 hours to prevent aspiration during the procedure. Obtaining coagulation study results is crucial to assess the risk of bleeding during and after the biopsy. Strict bedrest in a supine position is not necessary before the procedure. It is important to note that blood pressure medications should be carefully managed, but it is not a pre-procedure action. Keeping the client on bedrest or assessing for blood in the urine are interventions that are more relevant post-procedure to monitor for complications.
5. The patient will begin taking doxycycline to treat an infection. When should the nurse plan to give this medication?
- A. 1 hour before or 2 hours after a meal.
- B. with an antacid to minimize GI irritation.
- C. with food to improve absorption.
- D. with small sips of water.
Correct answer: C
Rationale: Doxycycline is a lipid-soluble tetracycline that is better absorbed when taken with milk products and food. Taking doxycycline with food helps improve its absorption. It should not be taken on an empty stomach, as this can decrease its effectiveness. Antacids can interfere with the absorption of tetracyclines, so they should not be taken together. While it is important to stay hydrated when taking medications, small sips of water are not specifically recommended for doxycycline administration.
