1. A client is being monitored while receiving bethanechol chloride (Urecholine) for urinary retention. Which of the following indicates a therapeutic effect of this medication?
- A. Increased heart rate
- B. Increased peristalsis
- C. Passage of flatus
- D. Urinary output of 50 mL per hour
Correct answer: D
Rationale: Bethanechol chloride (Urecholine) is administered to stimulate the bladder and treat urinary retention. The therapeutic effect is indicated by an increased urinary output, as it demonstrates the medication's ability to prompt the bladder to empty. Increased heart rate and passage of flatus are unrelated to the therapeutic effects of bethanechol. Although bethanechol can increase peristalsis, the primary therapeutic goal is to address urinary retention.
2. The endometrium is shed up to the basal layer during this phase of the menstrual cycle:
- A. Ovulation
- B. Regenerative
- C. Secretory
- D. Menstruation
Correct answer: D
Rationale: The correct answer is D. During the menstrual phase of the menstrual cycle, the endometrium is shed up to the basal layer. This shedding occurs as a result of decreased levels of estrogen and progesterone, leading to the breakdown and subsequent shedding of the endometrial lining. Choice A, ovulation, is incorrect as ovulation is the release of an egg from the ovary, which occurs during the mid-cycle. Choice B, regenerative, is incorrect as it does not specifically refer to the phase where the shedding of the endometrium occurs. Choice C, secretory, is incorrect as it refers to the phase where the endometrium thickens in preparation for possible implantation of a fertilized egg, not shedding.
3. A client with dyspnea is being admitted to the medical unit. To best prepare for the client's arrival, the nurse should ensure that the client's bed is in which position?
- A. Trendelenburg
- B. Supine
- C. Prone
- D. Fowler's
Correct answer: D
Rationale: Fowler's position (head elevated at 45-60 degrees) improves oxygenation by expanding the lungs, making it the best position for clients with dyspnea. Supine or prone positions restrict lung expansion, and Trendelenburg position (head down) can exacerbate breathing difficulties by increasing pressure on the lungs and diaphragm.
4. The nurse is instructing a 65-year-old female client diagnosed with osteoporosis. The most important instruction regarding exercise would be to
- A. Exercise doing weight-bearing activities
- B. Exercise to reduce weight
- C. Avoid exercise activities that increase the risk of fracture
- D. Exercise to strengthen muscles and thereby protect bones
Correct answer: A
Rationale: Weight-bearing exercises are crucial in managing osteoporosis as they help strengthen bones. Choice A is the correct answer because weight-bearing activities, such as walking, dancing, or weight training, help stimulate bone formation and strengthen bones, which is essential in managing osteoporosis. Choice B is incorrect as the primary focus should be on the type of exercise rather than weight reduction. Choice C is incorrect because avoiding exercise altogether can lead to further bone density loss, and it is important to engage in safe weight-bearing activities. Choice D is incorrect as the primary goal of exercise in osteoporosis is to improve bone density through weight-bearing activities.
5. The nurse is assessing an older adult client and determines that the client's left upper eyelid droops, covering more of the iris than the right eyelid. Which description should the nurse use to document this finding?
- A. Ptosis on the left eyelid.
- B. Nystagmus.
- C. Astigmatism.
- D. Exophthalmos.
Correct answer: A
Rationale: The correct answer is A: 'Ptosis on the left eyelid.' Ptosis is the term used to describe an eyelid droop that covers a large portion of the iris, which may be caused by issues with the oculomotor nerve or eyelid muscles. Choice B, 'Nystagmus,' refers to involuntary eye movements and is not related to eyelid drooping. Choice C, 'Astigmatism,' is a refractive error affecting vision due to an irregularly shaped cornea or lens, not an eyelid condition. Choice D, 'Exophthalmos,' is a protrusion of the eyeball associated with conditions like hyperthyroidism, not eyelid drooping.
