Nursing Elites

1. Which of the following is not a function of parathyroid hormone?

• A. moving calcium from bones to the bloodstream
• B. inhibiting renal tubular reabsorption of phosphorus
• C. promoting renal tubular reabsorption of calcium
• D. enhancing renal production of vitamin D metabolites

Correct answer: B

Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.

2. What sign might the nurse observe in a client with a high ammonia level?

• A. coma
• B. edema
• C. hypoxia
• D. polyuria

Correct answer: A

Rationale: Coma is a sign that a nurse might observe in a client with a high ammonia level. Elevated ammonia levels can lead to hepatic encephalopathy, a condition characterized by impaired brain function, which can progress to coma. Edema (choice B) is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia (choice C) is a condition of inadequate oxygen supply to tissues and is not directly related to high ammonia levels. Polyuria (choice D) refers to excessive urination and is not a typical sign of high ammonia levels.

3. After receiving a recent tattoo, someone should be screened for:

• A. tuberculosis.
• B. herpes.
• C. hepatitis.
• D. syphilis.

Correct answer: C

Rationale: After receiving a recent tattoo, screening for hepatitis is crucial due to the risk of blood-borne hepatitis B or C if strict sterile procedures are not followed during the tattooing process. Tuberculosis is an airborne pathogen and is not directly related to receiving a tattoo. Herpes and syphilis are infections spread through direct contact, such as sexual contact, and are not typically associated with tattooing.

4. What is distraction therapy?

• A. Focusing one's attention on stimuli other than pain.
• B. Cognitive reappraisal.
• C. The replacement of positive images of pain with other images.
• D. The use of medication and meditation.

Correct answer: A

Rationale: Distraction therapy involves directing attention away from pain towards positive stimuli, which can help reduce the perception of pain. Choice A is the correct answer as it accurately defines distraction therapy. Cognitive reappraisal (Choice B) involves changing the way one thinks about a situation to alter its emotional impact, which is different from distraction therapy. Choice C is incorrect because distraction therapy does not involve replacing images of pain with other images, but rather focusing on something unrelated. Choice D is incorrect as distraction therapy does not necessarily involve medication or meditation, but rather the redirection of attention.

5. The nurse should teach parents of small children that the most common type of first-degree burn is:

• A. scalding from hot bath water or spills.
• B. contact with hot surfaces such as stoves and fireplaces.
• C. contact with flammable liquids or gases resulting in flash burns.
• D. sunburn from lack of protection and overexposure.

Correct answer: D

Rationale: The correct answer is 'sunburn from lack of protection and overexposure.' First-degree burns primarily affect the outer layer of the skin and are commonly caused by overexposure to the sun without adequate protection, making it a significant concern for parents of small children. Choices A, B, and C describe other types of burns (scalding, contact with hot surfaces, and contact with flammable substances) that can cause more severe burns beyond the first-degree level. It is crucial for parents to be educated about sun safety measures to prevent sunburns in children.
