1. Which of the following statements should the nurse use to best describe a very low-calorie diet (VLCD) to a client?
- A. "This diet can be used when there is close medical supervision."?
- B. "This is a long-term treatment measure that assists obese people who can't lose weight."?
- C. "The VLCD consists of solid food items that are pureed to facilitate digestion and absorption."?
- D. "A VLCD contains very little protein."?
Correct answer: A
Rationale: The correct answer is, "This diet can be used when there is close medical supervision."? Very low-calorie diets (VLCDs) are used in the clinical treatment of obesity under close medical supervision. The diet is low in calories, high in quality protein, and has a minimum of carbohydrates to spare protein and prevent ketosis. Choice B is incorrect because VLCDs are typically short-term interventions. Choice C is incorrect because VLCDs usually consist of nutritionally complete liquid formulations, not solid food items that are pureed. Choice D is incorrect because VLCDs actually contain a high quality of protein, although the overall caloric content is very low.
2. A client receives a cervical intracavity radium implant as part of her therapy. A common side effect of a cervical implant is:
- A. creamy, pink-tinged vaginal drainage.
- B. stomatitis.
- C. constipation.
- D. xerostomia.
Correct answer: A
Rationale: The correct answer is 'creamy, pink-tinged vaginal drainage.' This side effect persists for 1 to 2 months after the removal of a cervical implant. Diarrhea, not constipation, is usually a side effect of cervical implants. Stomatitis and xerostomia are local side effects of radiation to the mouth, not associated with cervical implants. Therefore, choices B, C, and D are incorrect.
3. A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?
- A. Depressed function of the CNS
- B. Increased blood flow
- C. Decreased venous capacity
- D. Pain relief
Correct answer: C
Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.
4. A 70-year-old male who is recovering from a stroke exhibits signs of unilateral neglect. Which behavior is suggestive of unilateral neglect?
- A. The client is observed shaving only one side of his face.
- B. The client is unable to distinguish between two tactile stimuli presented simultaneously.
- C. The client is unable to complete a range of vision without turning his head side to side.
- D. The client is unable to carry out cognitive and motor activity at the same time.
Correct answer: A
Rationale: Unilateral neglect is a condition where a person ignores one side of their body. In this case, the behavior of shaving only one side of the face indicates neglect of the other side. This behavior is suggestive of unilateral neglect as the individual is failing to attend to one side of their body. Choices B, C, and D are not associated with unilateral neglect. Choice B refers to tactile agnosia, a condition where a person cannot recognize objects by touch, not related to ignoring one side of the body. Choice C describes a visual field cut, which is a different visual deficit. Choice D relates to dual-task interference, not specific to ignoring one side of the body.
5. Which physiologic mechanism best describes the function of the sodium-potassium pump?
- A. active transport
- B. diffusion
- C. filtration
- D. osmosis
Correct answer: A
Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.
