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 client in a physician's office has just made an appointment for an exercise stress test. The client should be instructed to:
- A. Wear sweatpants and a heavy sweatshirt
- B. Eat a small meal just before the procedure
- C. Wear comfortable rubber-soled shoes such as sneakers
- D. Avoid consuming caffeine for 30 minutes before the procedure
Correct Answer: C
Rationale: The client should wear comfortable rubber-soled shoes, such as sneakers, for the exercise stress test. This choice ensures safety and stability during the procedure. Wearing sweatpants and a heavy sweatshirt (Choice A) would not be appropriate as the client needs to wear light, loose, comfortable clothing. Eating a small meal just before the procedure (Choice B) could lead to discomfort during the test. Avoiding caffeine for 30 minutes before the procedure (Choice D) is not a specific instruction related to the attire or preparation for the test.
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 delegating to an unlicensed assistive personnel (UAP) the task of completing a bladder scan examination for a client, the nurse evaluates the UAP's performance. Which action by the UAP indicates the nurse must provide additional instructions when delegating this task?
- A. Selecting the female icon for all female clients and the male icon for all male clients
- B. Explaining to the client, 'This test measures the amount of urine in your bladder.'
- C. Applying ultrasound gel to the scanning head and cleaning it after use
- D. Taking at least two readings using the aiming icon to position the scanning head
Correct Answer: A
Rationale: The correct answer is A because the UAP should select the female icon for women who have not had a hysterectomy to allow the scanner to subtract the volume of the uterus from readings. If a woman has had a hysterectomy, the UAP should choose the male icon. Choice B is incorrect as it is essential for the UAP to explain the procedure to the client to ensure understanding. Choice C is incorrect because applying ultrasound gel to the scanning head and cleaning it after use are appropriate actions. Choice D is incorrect as it is necessary for the UAP to take at least two readings using the aiming icon to position the scanning head accurately for an effective bladder scan examination.
A client who is mouth breathing is receiving oxygen by face mask. The nursing assistant asks the nurse why a water bottle is attached to the oxygen tubing near the wall oxygen outlet. The nurse responds that the primary purpose of the water is to:
- A. Prevent the client from getting a nosebleed
- B. Give the client added fluid by way of the respiratory tree
- C. Humidify the oxygen that is bypassing the client's nose
- D. Prevent fluid loss from the lungs during mouth breathing
Correct Answer: C
Rationale: The purpose of the water bottle is to humidify the oxygen that is bypassing the nose during mouth breathing. When a client breathes through the mouth, the oxygen delivered by the face mask bypasses the natural humidification provided by the nasal passages. Therefore, the water bottle attachment helps to add moisture to the oxygen, preventing dryness and irritation to the respiratory tract. Choices A, B, and D are incorrect. Clients breathing through the mouth are not at risk for nosebleeds, do not receive added fluid through the respiratory tree, and do not experience fluid loss from the lungs due to mouth breathing.
A client with functional urinary incontinence is being taught by a nurse. Which statement should the nurse include in this client's teaching?
- A. Clean around your catheter daily with soap and water.
- B. Wash the vaginal weights with a 10% bleach solution after each use.
- C. Informing about available operations to repair your bladder.
- D. Buy slacks with elastic waistbands that are easy to pull down.
Correct Answer: D
Rationale: Functional urinary incontinence is not related to bladder issues but rather to difficulties with ambulation or accessing the toilet. The goal is to help the client manage clothing independently. Elastic waistband slacks that are easy to pull down facilitate timely access to the toilet. Choices A and B are unrelated and not applicable to functional urinary incontinence. Choice C is incorrect as surgeries to repair the bladder are not indicated for functional urinary incontinence.
