1. A client is being treated with a tricyclic antidepressant (TCA). Which side effect should the nurse monitor for?
- A. Constipation and urinary retention.
- B. Increased appetite and weight loss.
- C. Sedation and blurred vision.
- D. Insomnia and dry mouth.
Correct answer: A
Rationale: The correct answer is A: Constipation and urinary retention. Tricyclic antidepressants (TCAs) are known to have anticholinergic side effects, which include constipation and urinary retention. These side effects occur due to the inhibition of cholinergic receptors, leading to decreased gastrointestinal motility and relaxation of the detrusor muscle in the bladder. Choices B, C, and D are incorrect because increased appetite, weight loss, sedation, blurred vision, insomnia, and dry mouth are not typically associated with the use of TCAs. Monitoring for constipation and urinary retention is essential to prevent complications and ensure the client's safety.
2. The nurse is caring for a client with a chest tube in place following a pneumothorax. Which assessment finding requires immediate intervention?
- A. Oxygen saturation of 94%
- B. Crepitus around the insertion site
- C. Subcutaneous emphysema
- D. Blood pressure of 110/70 mmHg
Correct answer: C
Rationale: Subcutaneous emphysema is the assessment finding that requires immediate intervention in a client with a chest tube following a pneumothorax. Subcutaneous emphysema can indicate a pneumothorax recurrence or air leak, which can compromise respiratory function and lead to serious complications. Oxygen saturation of 94% may be concerning but does not require immediate intervention as it is still within an acceptable range. Crepitus around the insertion site is common after chest tube placement and may not always indicate a problem. A blood pressure of 110/70 mmHg is within normal limits and does not require immediate intervention in this context.
3. A client with elevated levels of antidiuretic hormone (ADH) triggers the release of this hormone due to which disorder?
- A. Pneumonia
- B. Dehydration
- C. Renal failure
- D. Edema
Correct answer: B
Rationale: Antidiuretic hormone (ADH) increases tubular permeability to water, causing more water absorption into the capillaries. ADH is released in response to a rising extracellular fluid osmolarity, such as in dehydration. Pneumonia, renal failure, and edema do not typically lead to the release of ADH. Pneumonia is an inflammatory lung condition, renal failure affects kidney function, and edema is the accumulation of excess fluid in the tissues, none of which directly stimulate the release of ADH.
4. A client in the emergency department is severely dehydrated and is prescribed 3 L of intravenous fluid over 6 hours. At what rate (mL/hr) should the nurse set the intravenous pump to infuse the fluids? (Record your answer using a whole number.)
- A. 500 mL/hr
- B. 400 mL/hr
- C. 550 mL/hr
- D. 600 mL/hr
Correct answer: A
Rationale: To calculate the rate of the intravenous pump, divide the total volume of fluid (3 L = 3000 mL) by the total time in hours (6 hours), which equals 500 mL/hr. The correct answer is A. Choice B (400 mL/hr) is incorrect as it would result in a slower infusion rate. Choice C (550 mL/hr) and Choice D (600 mL/hr) are incorrect as they would result in a faster infusion rate, exceeding the prescribed amount of fluid to be infused over 6 hours.
5. A 60-year-old male client had a hernia repair in an outpatient surgery clinic. He is awake and alert but has not been able to void since he returned from surgery 6 hours ago. He received 1000 mL of IV fluid. Which action would be most likely to help him void?
- A. Have him drink several glasses of water
- B. Crede the bladder from the bottom to the top
- C. Assist him to stand by the side of the bed to void
- D. Wait 2 hours and have him try to void again
Correct answer: C
Rationale: Assisting the client to stand by the side of the bed to void is the most appropriate action in this situation. Standing to void often helps relieve the bladder, especially after surgery. Option A, having him drink several glasses of water, may not be as effective as the client might already be adequately hydrated. Option B, Crede maneuver, is a technique for emptying the bladder by applying manual pressure and is not the first-line intervention for a client who cannot void post-surgery. Option D, waiting 2 hours before trying to void again, may delay necessary intervention if the client is experiencing urinary retention.
