Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?
- A. skin
- B. adipose tissue
- C. skeletal muscle
- D. myocardium
Correct Answer: D
Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

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.
Which of the following foods might a client with hypercholesterolemia need to decrease intake of?
- A. broiled catfish
- B. hamburgers
- C. wheat bread
- D. fresh apples
Correct Answer: B
Rationale: A client with hypercholesterolemia needs to decrease intake of foods that are high in cholesterol. Red meats like hamburgers are high in cholesterol, so their consumption should be reduced. Broiled catfish, wheat bread, and fresh apples are not high in cholesterol and do not need to be decreased in the client's diet. Therefore, the correct answer is hamburgers, as they are more likely to contribute to elevated cholesterol levels compared to the other options provided.
A client with which of the following conditions is at risk for developing a high ammonia level?
- A. renal failure
- B. psoriasis
- C. lupus
- D. cirrhosis
Correct Answer: D
Rationale: A client with cirrhosis is at risk for developing a high ammonia level due to impaired liver function. The liver normally converts ammonia into urea for excretion. In cirrhosis, this process is compromised, leading to elevated ammonia levels in the blood. Renal failure, psoriasis, and lupus do not typically cause high ammonia levels. Renal failure affects kidney function, while psoriasis and lupus are autoimmune conditions that do not directly impact ammonia metabolism.
Following a recent tattoo, someone should be screened for:
- A. tuberculosis.
- B. herpes.
- C. hepatitis.
- D. syphilis.
Correct Answer: C
Rationale: Following a recent tattoo, someone should be screened for hepatitis. Tattooing puts a client at risk for blood-borne hepatitis B or C if strict sterile procedures are not followed. Tuberculosis is an airborne pathogen, while herpes and syphilis are spread through direct contact like sexual activity. Therefore, hepatitis is the most relevant infection to screen for after getting a tattoo.
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.
