Which of the following represents a normal serum potassium level?
- A. 1.5 mEq/L
- B. 3.0 mEq/L
- C. 4.0 mEq/L
- D. 6.0 mEq/L
Correct Answer: C
Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

Ms. Petty is having difficulty falling asleep. Which of the following measures promote sleep?
- A. exercising vigorously for 20 minutes each night starting at 9:30 p.m.
- B. taking a cool shower and drinking a hot cup of tea
- C. watching TV nightly until midnight
- D. getting a back rub and drinking a glass of warm milk
Correct Answer: D
Rationale: Getting a back rub and drinking a glass of warm milk are appropriate measures to promote sleep as they can help relax the body and induce sleepiness. Exercising vigorously, as suggested in choice A, can be counterproductive as it stimulates the body rather than relaxing it, making it harder to fall asleep. Choice B, taking a cool shower and drinking a hot cup of tea, may also increase alertness due to the temperature changes and the caffeine in tea, which can interfere with falling asleep. Watching TV until midnight, as in choice C, exposes the individual to blue light and mental stimulation, making it harder to fall asleep. Therefore, choice D is the best option to promote sleep in this scenario.
In an obstetrical emergency, which of the following actions should the nurse perform first after the baby delivers?
- A. Place extra padding under the mother to absorb blood from the delivery.
- B. Cut the umbilical cord using sterile scissors.
- C. Suction the baby's mouth and nose.
- D. Wrap the baby in a clean blanket to preserve warmth.
Correct Answer: C
Rationale: In an obstetrical emergency, the immediate action the nurse should take after the baby delivers is to suction the baby's mouth and nose to ensure the infant can breathe properly. This helps clear any potential obstructions and establish a clear airway. Cutting the umbilical cord (Choice B) and wrapping the baby in a clean blanket (Choice D) are important steps but should come after ensuring the baby's airway is clear. Placing extra padding under the mother (Choice A) is not a priority in this emergency situation as the focus should be on the baby's immediate needs for breathing and airway clearance.
The client is being taught about the use of Rifampin for prophylaxis following exposure to meningitis. What change in bodily functions should the client be informed about?
- A. The client's urine may turn blue.
- B. The client remains infectious to others for 48 hours.
- C. The client's contact lenses may be stained orange.
- D. The client's skin may take on a crimson glow.
Correct Answer: C
Rationale: Rifampin has the unusual effect of turning body fluids an orange color. Soft contact lenses might become permanently stained. Clients should be taught about these side effects to avoid unnecessary concern. Option A is incorrect as Rifampin does not cause the urine to turn blue. Option B is incorrect as the client is not infectious to others due to taking Rifampin for prophylaxis. Option D is incorrect as Rifampin does not cause the skin to take on a crimson glow.
What should be the primary action for a client who has just vomited 300 cc of bright red blood?
- A. Document the vomiting.
- B. Increase IV fluids.
- C. Get a complete blood count.
- D. Check the blood pressure.
Correct Answer: D
Rationale: The correct first action for a client who has just vomited 300 cc of bright red blood is to check the blood pressure. This assessment is crucial to evaluate for hypotension, which could indicate significant blood loss and the need for immediate intervention. Documenting the vomiting is important for the client's medical record but not the initial priority. Increasing IV fluids and getting a complete blood count are necessary steps but should follow the assessment of the client's hemodynamic status.
Which of the following nursing diagnoses is most appropriate for a client with a new colostomy?
- A. Excess Fluid Volume
- B. Risk for Aspiration
- C. Disturbed Body Image
- D. Urinary Retention
Correct Answer: C
Rationale: Disturbed Body Image is the most appropriate nursing diagnosis for a client with a new colostomy. A new colostomy can significantly impact a person's body image and self-esteem due to the physical changes it brings. This can lead to emotional distress, adjustment issues, and concerns about body image. Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are not directly related to the psychosocial impact of a new colostomy and are therefore not as relevant in this context. While Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are important nursing diagnoses, they are not the priority when considering the psychological and emotional effects of a new colostomy.
