1. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding requires immediate intervention?
- A. Serum glucose of 300 mg/dL
- B. Serum potassium of 5.5 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Positive urine ketones
Correct answer: C
Rationale: A serum bicarbonate level of 18 mEq/L indicates metabolic acidosis in a client with DKA, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis, which is reflected by a low serum bicarbonate level. Correcting the low serum bicarbonate is crucial to normalize the metabolic acidosis and improve the client's condition. While elevated serum glucose (choice A) and urine ketones (choice D) are characteristic of DKA, addressing the metabolic acidosis takes precedence. Serum potassium (choice B) levels may also need monitoring and management, but correcting the acidosis is the priority to prevent complications like cardiovascular collapse.
2. When a male Korean-American client looks away when asked by the nurse to describe his problem, what is the best initial nursing action?
- A. Ask for assistance from social services to find a Korean interpreter.
- B. Establish indirect eye contact with the client.
- C. Allow several minutes for the client to respond.
- D. Repeat the question using simpler language.
Correct answer: C
Rationale: In this scenario, the best initial nursing action is to allow several minutes for the client to respond. This approach respects the cultural norms of the client, as in some cultures, direct eye contact may be perceived as disrespectful or intrusive. By giving the client time to gather his thoughts and respond at his own pace, the nurse promotes effective communication and demonstrates cultural sensitivity. Asking for assistance from social services to find a Korean interpreter (Choice A) may be necessary for further communication but is not the best initial action. Establishing indirect eye contact (Choice B) may still make the client uncomfortable. Repeating the question using simpler language (Choice D) may not address the underlying cultural aspect affecting the client's response.
3. A client with liver cirrhosis is admitted with ascites and jaundice. Which assessment finding is most concerning?
- A. Serum albumin of 3.0 g/dL
- B. Bilirubin of 3.0 mg/dL
- C. Ammonia level of 80 mcg/dL
- D. Prothrombin time of 18 seconds
Correct answer: C
Rationale: An ammonia level of 80 mcg/dL is elevated and concerning in a client with liver cirrhosis, as it may indicate hepatic encephalopathy. Elevated ammonia levels can lead to cognitive impairment, altered mental status, and even coma. Serum albumin, bilirubin, and prothrombin time are also important markers in liver cirrhosis but are not as directly associated with the risk of hepatic encephalopathy as elevated ammonia levels.
4. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?
- A. Low bioavailability
- B. Rapid onset of action
- C. Short half-life
- D. Narrow therapeutic index
Correct answer: D
Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
5. The nurse teaches an adolescent male client how to use a metered dose inhaler. What instruction should the nurse provide?
- A. Secure the mouthpiece under the tongue.
- B. Press down on the device after breathing in fully.
- C. Move the device one to two inches away from the mouth.
- D. Breathe out slowly and deeply while compressing the device.
Correct answer: C
Rationale: The correct instruction for using a metered dose inhaler is to move the device one to two inches away from the mouth. This distance helps ensure effective delivery of the medication directly to the airways. Choice A is incorrect as the mouthpiece should be placed between the lips, not under the tongue. Choice B is incorrect because the device should be pressed down before breathing in, not after. Choice D is wrong because the patient should breathe out fully before using the inhaler, not while compressing the device.
