1. After a laparoscopic cholecystectomy, what is the most important instruction the nurse should give the client regarding post-operative care at home?
- A. Avoid lifting heavy objects for at least a week.
- B. Follow a low-fat diet.
- C. Monitor the incision sites for signs of infection.
- D. Resume normal activities as tolerated.
Correct answer: C
Rationale: Monitoring the incision sites for signs of infection is crucial after a laparoscopic cholecystectomy. Infections can lead to serious complications if not detected early. While avoiding heavy lifting and following a low-fat diet are important aspects of recovery, monitoring for infection takes precedence as it directly impacts the client's immediate post-operative well-being. Therefore, option C is the correct answer as it addresses the most critical aspect of post-operative care.
2. During an inspection of a client's fingernails, the nurse notices a suspected abnormality in the shape and character of the nails. Which finding should the nurse document?
- A. Clubbed nails
- B. Splinter hemorrhages
- C. Longitudinal ridges
- D. Koilonychia or spoon nails
Correct answer: A
Rationale: Clubbed nails are a significant finding in clients with chronic hypoxia or lung disease. This abnormality is characterized by an increased curvature of the nails and softening of the nail bed. It can indicate underlying health conditions such as respiratory or cardiovascular issues. Splinter hemorrhages (B) are small areas of bleeding under the nails, typically associated with infective endocarditis. Longitudinal ridges (C) are often a normal age-related change in the nails. Koilonychia or spoon nails (D) present as a concave shape of the nails and are commonly seen in clients with iron deficiency anemia or hemochromatosis. Therefore, documenting clubbed nails is the most relevant abnormality to report and investigate further.
3. You are teaching students about how hyperosmotic agents (osmotic diuretics) are used to treat intracranial pressure. Which of the following is NOT one of the functions of hyperosmotic agents?
- A. Reduces brain metabolism and systemic blood pressure
- B. Reduces cerebral edema
- C. Dehydrates the brain
- D. Draws fluids from extravascular spaces into the plasma
Correct answer: A
Rationale: Hyperosmotic agents primarily work by reducing cerebral edema, dehydrating the brain, and drawing fluids from extravascular spaces into the plasma. However, they do not have a direct effect on reducing brain metabolism or systemic blood pressure. Therefore, the correct answer is A. Choice B is correct as hyperosmotic agents do help in reducing cerebral edema. Choice C is accurate as hyperosmotic agents dehydrate the brain. Choice D is also true as these agents draw fluids from extravascular spaces into the plasma.
4. The PN administered darbepoetin alfa to a client with chronic kidney disease (CKD). Which serum laboratory value should the PN monitor to assess the effectiveness of this drug?
- A. Calcium
- B. Phosphorus
- C. Hemoglobin
- D. White blood cell count
Correct answer: C
Rationale: Darbepoetin alfa is used to stimulate red blood cell production in clients with CKD. Monitoring hemoglobin levels is essential to assess the effectiveness of the treatment and to adjust the dosage to avoid complications such as hypertension or thrombosis. Monitoring calcium (Choice A), phosphorus (Choice B), or white blood cell count (Choice D) is not directly related to the effectiveness of darbepoetin alfa in treating anemia associated with CKD.
5. What is the primary cause of diabetic ketoacidosis (DKA)?
- A. Insulin deficiency
- B. Overhydration
- C. Excess carbohydrate intake
- D. Excess insulin
Correct answer: A
Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.
