The healthcare provider is caring for a patient who is receiving an intravenous antibiotic. The patient has a serum drug trough of 1.5 mcg/mL. The normal trough for this drug is 1.7 mcg/mL to 2.2 mcg/mL. What will the healthcare provider expect the patient to experience?
- A. Inadequate drug effects
- B. Increased risk of superinfection
- C. Minimal adverse effects
- D. Slowed onset of action
Correct Answer: A
Rationale: A serum drug trough level below the normal range (1.7 mcg/mL to 2.2 mcg/mL) indicates that the medication concentration is insufficient to provide therapeutic effects, leading to inadequate drug effects. A low trough level does not directly correlate with an increased risk of superinfection, minimal adverse effects, or a slowed onset of action, as these are more related to the drug's concentration within the therapeutic range.

A nurse cares for clients with urinary incontinence. Which types of incontinence are correctly paired with their clinical manifestations? (Select all that apply.)
- A. Stress incontinence - Urine loss with physical exertion
- B. Urge incontinence - Large amount of urine with each occurrence
- C. Overflow incontinence - Constant dribbling of urine
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D, as all the choices are correctly paired with their clinical manifestations. Stress incontinence is characterized by urine loss with physical exertion, coughing, sneezing, or exercising. Urge incontinence presents with a sudden and strong urge to void, often accompanied by a large amount of urine released during each occurrence. Overflow incontinence occurs when the bladder is distended, leading to a constant dribbling of urine. Functional incontinence, not mentioned in the options, is the leakage of urine due to factors unrelated to a lower urinary tract disorder. Reflex incontinence, also not mentioned, is a condition resulting from abnormal detrusor contractions.
After teaching a client with early polycystic kidney disease (PKD) about nutritional therapy, the nurse assesses the client's understanding. Which statement made by the client indicates a correct understanding of the teaching?
- A. I will take a laxative every night before going to bed.
- B. I must increase my intake of dietary fiber and fluids.
- C. I shall only use salt when I am cooking my own food.
- D. I'll eat white bread to minimize gastrointestinal gas.
Correct Answer: B
Rationale: Choice B is the correct answer. Clients with PKD often experience constipation, which can be managed by increasing their intake of dietary fiber and fluids. This helps promote bowel regularity. Laxatives should be used cautiously and not as a routine solution. Choice A is incorrect as regular laxative use is not recommended. Choice C is incorrect as a low-salt diet is typically advised for clients with PKD, not just limiting salt while cooking. Choice D is incorrect as white bread is low in fiber and not beneficial for managing constipation, which is common in PKD.
A client has a chest drainage system in place. The fluid in the water seal chamber rises and falls during inspiration and expiration. The nurse interprets this finding as an indication that:
- A. The tube is patent
- B. There is probably a kink in the tubing
- C. Suction should be added to the system
- D. The client is retaining airway secretions
Correct Answer: A
Rationale: The correct answer is A: 'The tube is patent.' When the fluid in the water seal chamber rises and falls during inspiration and expiration, it indicates that the chest tube is patent, allowing for proper drainage. Choice B is incorrect because a kink in the tubing would obstruct the flow of fluid, leading to abnormal fluctuations in the water seal chamber. Choice C is incorrect as adding suction to the system is not indicated based on the described finding. Choice D is incorrect as the rising and falling of fluid in the water seal chamber is not indicative of the client retaining airway secretions.
Blood is drawn from a client with suspected uric acid calculi for a serum uric acid determination. Which value does the nurse recognize as a normal uric acid level?
- A. 1.7 mg/dL
- B. 5.8 mg/dL
- C. 8.9 mg/dL
- D. 12.8 mg/dL
Correct Answer: B
Rationale: The normal range for uric acid is 4.5 to 8 mg/dL for males and 2.5 to 6.2 mg/dL for females. A uric acid level of 5.8 mg/dL falls within the normal range. Choices A, C, and D are outside the normal reference range, making them incorrect. Choice B is the correct answer as it aligns with the typical uric acid levels in the blood.
After educating a client with hypertension secondary to renal disease, the nurse assesses the client's understanding. Which statement made by the client indicates a need for additional teaching?
- A. I can prevent more damage to my kidneys by managing my blood pressure.
- B. If I have increased urination at night, I need to drink less fluid during the day.
- C. I need to see the registered dietitian to discuss limiting my protein intake.
- D. It is important that I take my antihypertensive medications as directed.
Correct Answer: B
Rationale: Choice B is incorrect because the client should not restrict fluids during the day due to increased urination at night. Clients with renal disease may be prescribed fluid restrictions, and they should be thoroughly assessed for potential dehydration. To decrease increased nocturnal voiding, clients should consume fluids earlier in the day. Choices A, C, and D are correct statements. Managing blood pressure is crucial to slow the progression of renal dysfunction. Limiting protein intake is important in renal disease management, and clients should be referred to a dietitian as needed. Taking antihypertensive medications as directed is essential for blood pressure control.
