1. When using an open irrigation technique to irrigate a client's indwelling urinary catheter, which of the following actions should the nurse take?
- A. Place the client in a side-lying position
- B. Instill 15 mL of irrigation fluid into the catheter with each flush
- C. Subtract the amount of irrigant used from the client's urine output
- D. Perform the irrigation using a 20 mL syringe
Correct answer: C
Rationale: The correct action for the nurse to take when using an open irrigation technique on a client with an indwelling urinary catheter is to subtract the amount of irrigant used from the client's urine output. This calculation helps ensure an accurate measurement of the client's actual urine output by accounting for the irrigation fluid introduced into the catheter. Placing the client in a side-lying position (Choice A) is not directly related to the irrigation procedure. Instilling a specific volume of irrigation fluid (Choice B) may vary depending on the client's condition and the healthcare provider's order. Using a 20 mL syringe for irrigation (Choice D) is a matter of equipment choice and does not directly impact the calculation of urine output in this context.
2. Which nursing action prevents injury to a client's eye during the administration of eye drops?
- A. Holding the tip of the container above the conjunctival sac
- B. Rinsing the eye with saline before administration
- C. Placing the client in a supine position
- D. Pressing gently on the lower eyelid to open the eye
Correct answer: A
Rationale: The correct nursing action to prevent injury to a client's eye during the administration of eye drops is to hold the tip of the container above the conjunctival sac. This technique helps to prevent direct contact between the container and the eye, reducing the risk of injury. Rinsing the eye with saline before administration (Choice B) is not a standard practice and may not necessarily prevent injury. Placing the client in a supine position (Choice C) is not directly related to preventing eye injury during eye drop administration. Pressing gently on the lower eyelid to open the eye (Choice D) is not recommended as it can potentially cause injury or discomfort to the client.
3. A healthcare professional is preparing to administer metoprolol 200 mg PO daily. The medication available is metoprolol 100 mg/tablet. How many tablets should the healthcare professional administer? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 1 tablet
- B. 2 tablets
- C. 0.5 tablet
- D. 4 tablets
Correct answer: B
Rationale: To administer 200 mg of metoprolol using 100 mg tablets, the healthcare professional should give 2 tablets. Each tablet contains 100 mg of metoprolol, so 2 tablets will provide the required 200 mg dose. Choice A is incorrect because 1 tablet would only provide 100 mg, which is insufficient. Choice C is incorrect as fractions of tablets are usually not used in practice to ensure accurate dosing. Choice D is incorrect as it would result in an overdose, providing 400 mg instead of the prescribed 200 mg.
4. During an admission history, a client tells a nurse that she is under a lot of stress. Which of the following physiological responses should the nurse expect to increase as a result of stress?
- A. Blood glucose - a common stress response.
- B. Intestinal peristalsis - should decrease due to stress.
- C. Peripheral blood vessels diameter - can vary in response to stress.
- D. Urine output - may vary but not a typical stress response.
Correct answer: A
Rationale: The correct answer is A. Stress typically increases blood glucose levels due to the release of stress hormones like cortisol and adrenaline. Elevated blood glucose helps provide energy for the body to cope with the stressful situation. Choice B is incorrect because intestinal peristalsis, the movement of the intestines, is more likely to decrease under stress due to the 'fight or flight' response. Choice C is incorrect as peripheral blood vessels' diameter may vary in response to stress, with both constriction and dilation possible. Choice D is incorrect as urine output may increase or decrease depending on individual differences and the specific stress response, but it is not a typical or direct physiological response to stress.
5. A client is evaluated by a nurse regarding the use of a sequential compression device. Which of the following client statements indicates understanding of the device's purpose?
- A. “This device will keep me from developing skin sores.”
- B. “This device will keep the blood circulating in my leg.”
- C. “This device will prevent my leg muscles from weakening.”
- D. “This device will maintain the health of my joints.”
Correct answer: B
Rationale: The correct answer is B because sequential compression devices are utilized to enhance circulation and prevent clot formation in the legs. Option A is incorrect because these devices are not primarily meant to prevent skin sores. Option C is incorrect because the devices do not directly address muscle weakness. Option D is incorrect as the main purpose of sequential compression devices is not related to joint health.
