1. A client with acute glomerulonephritis (GN) is being evaluated by a nurse. Which manifestation should the nurse recognize as a positive response to the prescribed treatment?
- A. The client has lost 11 pounds in the past 10 days.
- B. The client’s urine specific gravity is 1.048.
- C. No blood is observed in the client’s urine.
- D. The client’s blood pressure is 152/88 mm Hg.
Correct answer: A
Rationale: A weight loss of 11 pounds in the past 10 days indicates fluid loss, a positive response to treatment for acute glomerulonephritis. It signifies that the glomeruli are functioning adequately to filter excess fluid. A urine specific gravity of 1.048 is high, indicating concentrated urine, which is not a positive response in this context. Blood in the urine is not a typical finding in glomerulonephritis, so its absence is expected and does not indicate a positive response to treatment. A blood pressure of 152/88 mm Hg is elevated and may suggest kidney damage or fluid overload, which are not positive responses to treatment.
2. A patient presents with severe chest pain radiating to the left arm. Which of the following diagnostic tests is the priority?
- A. Complete blood count (CBC)
- B. Electrocardiogram (ECG)
- C. Chest X-ray
- D. Serum electrolytes
Correct answer: B
Rationale: In a patient presenting with severe chest pain radiating to the left arm, the priority diagnostic test is an Electrocardiogram (ECG) to assess for myocardial infarction. An ECG can quickly identify changes indicative of ischemia or infarction, guiding prompt management. A Complete Blood Count (CBC) may provide some information but is not the primary test for evaluating chest pain related to myocardial infarction. A Chest X-ray can be useful in assessing lung pathologies or certain cardiac conditions; however, it does not provide immediate information on myocardial infarction, making it a secondary option in this scenario. Serum electrolytes may become important in later stages but do not offer immediate insights into myocardial infarction. Therefore, they are a lower priority compared to obtaining an ECG for timely diagnosis and intervention.
3. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?
- A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
- B. A serum drug level greater than the MEC broadens the spectrum of the drug.
- C. A serum drug level greater than the MEC helps eradicate bacterial infections.
- D. A serum drug level greater than the MEC increases the therapeutic index.
Correct answer: C
Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.
4. A client who was in a motor vehicle collision was admitted to the hospital, and the right knee was placed in skeletal traction. The nurse has documented this nursing diagnosis in the client's medical record: 'Potential for impairment of skin integrity related to immobility from traction.' Which nursing intervention is indicated based on this diagnosis statement?
- A. Release the traction every 4 hours to provide skin care.
- B. Turn the client for back care while suspending traction.
- C. Provide back and skin care while maintaining the traction.
- D. Give back care after the client is released from traction.
Correct answer: C
Rationale: The correct nursing intervention indicated based on the nursing diagnosis 'Potential for impairment of skin integrity related to immobility from traction' is to provide back and skin care while maintaining the traction. This intervention is crucial for maintaining the client's skin integrity and preventing potential complications. Releasing the traction every 4 hours (Choice A) may disrupt the treatment plan and compromise the effectiveness of traction. Turning the client for back care while suspending traction (Choice B) does not address the need for skin care while the client is in traction. Giving back care after the client is released from traction (Choice D) neglects the immediate need to prevent skin impairment while in traction. Therefore, providing back and skin care while maintaining the traction (Choice C) is the most appropriate intervention in this scenario.
5. The healthcare provider assesses a client with cirrhosis and finds 4+ pitting edema of the feet and legs, and massive ascites. Which mechanism contributes to edema and ascites in clients with cirrhosis?
- A. Hyperaldosteronism causing increased sodium transport ion in renal tubules
- B. Decreased portacaval pressure with greater collateral circulation
- C. Decreased renin-angiotensin response related to increased renal blood flow
- D. Hypoalbuminemia that results in decreased colloidal oncotic pressure
Correct answer: D
Rationale: In clients with cirrhosis, hypoalbuminemia leads to decreased colloidal oncotic pressure. This reduction in oncotic pressure contributes to the development of edema in the feet and legs (pitting edema) and ascites in the abdomen. Hyperaldosteronism (choice A) would lead to sodium retention but is not the primary mechanism behind edema and ascites in cirrhosis. Decreased portacaval pressure with greater collateral circulation (choice B) is not directly related to the pathophysiology of edema and ascites in cirrhosis. Decreased renin-angiotensin response related to increased renal blood flow (choice C) does not play a significant role in the development of edema and ascites in cirrhosis compared to the impact of hypoalbuminemia on colloidal oncotic pressure.
