Nursing Elites

1. How often should the intravenous tubing on total parenteral nutrition solutions be changed?

• A. every 24 hours
• B. every 36 hours
• C. every 48 hours
• D. every 72 hours

Correct answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.

2. A client complains that her skin is redder than normal. The nurse notes the client's skin, documents hyperemia, and explains to the client that this condition is caused by which factor?

• A. Constriction of the underlying blood vessels
• B. An increased amount of bilirubin in the blood
• C. Increased perfusion of the surrounding tissues
• D. Excess blood in the dilated superficial capillaries

Correct answer: D

Rationale: Hyperemia is an excess of blood in a part of the body. The skin over a hyperemic area usually becomes reddened or warm. The condition is caused by increased blood flow, local relaxation of arterioles, or obstruction of the outflow of blood from an area. Choice A is incorrect because constriction of blood vessels would lead to decreased blood flow, not excess blood. Choice B is incorrect as an increased amount of bilirubin in the blood is related to jaundice, not hyperemia. Choice C is incorrect because increased perfusion of the surrounding tissues would cause redness, not hyperemia.

3. 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 tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.

4. When assessing a client with deep pitting edema, with the indentation remaining for a short time and visible leg swelling, how should a nurse document this finding?

• A. 1+ edema
• B. 2+ edema
• C. 3+ edema
• D. 4+ edema

Correct answer: C

Rationale: The correct answer is 3+ edema. When assessing for edema, the nurse presses thumbs against the ankle malleolus or the tibia. If the skin retains an indentation, it indicates pitting edema. The grading scale for pitting edema includes: 1+ for mild pitting with slight indentation and no perceptible leg swelling, 2+ for moderate pitting where the indentation subsides rapidly, 3+ for deep pitting with an indentation remaining briefly and visible leg swelling, and 4+ for very deep pitting with a long-lasting indentation and significant leg swelling. Choices A, B, and D do not accurately represent the severity of the edema described in the scenario.

5. Which of the following substances need to be assessed when completing a family health assessment?

• A. coffee, tea, cola, cocoa, and other substances
• B. alcohol, tobacco, and illegal substances
• C. medicines prescribed by a physician
• D. all of the above

Correct answer: D

Rationale: When completing a family health assessment, it is essential to assess all substances consumed by family members, including coffee, tea, cola, cocoa, alcohol, tobacco, illegal substances, and medicines prescribed by a physician. Understanding the complete picture of substance use within the family is crucial for identifying potential health risks and providing appropriate care. Choice D, 'all of the above,' is the correct answer as it encompasses the comprehensive assessment of all substances. Choices A, B, and C are incorrect as they only present partial aspects of substance assessment and do not cover the full range of substances that should be evaluated in a family health assessment.
