Nursing Elites

1. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

2. A nurse is providing information to a group of pregnant clients and their partners about the psychosocial development of an infant. Using Erikson's theory of psychosocial development, the nurse tells the group that infants have which developmental need?

• A. Must have needs ignored for short periods to develop a healthy personality
• B. Need to rely on the fact that their needs will be met
• C. Need to experience frustration, so it is best to allow an infant to cry for a while before meeting his or her needs
• D. Need to tolerate a great deal of frustration and discomfort to develop a healthy personality

Correct answer: B

Rationale: According to Erikson's theory of psychosocial development, infants struggle to establish a sense of basic trust rather than a sense of basic mistrust in their world, their caregivers, and themselves. If provided with consistent satisfying experiences that are delivered in a timely manner, infants come to rely on the fact that their needs are met and that, in turn, they will be able to tolerate some degree of frustration and discomfort until those needs are met. This sense of confidence is an early form of trust and provides the foundation for a healthy personality. Therefore, options A, C, and D are incorrect as they do not align with Erikson's theory that emphasizes the importance of infants trusting that their needs will be met.

3. How often should the nurse change the intravenous tubing on total parenteral nutrition solutions?

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

Correct answer: A

Rationale: The correct answer is 'every 24 hours.' Changing the intravenous tubing on total parenteral nutrition solutions every 24 hours is crucial due to the high risk of bacterial growth. Bacterial contamination can lead to serious infections in patients receiving total parenteral nutrition. Choices B, C, and D are incorrect because waiting longer intervals between tubing changes increases the risk of bacterial contamination and infection, compromising patient safety. It is essential to maintain a strict 24-hour schedule to minimize the risk of complications associated with bacterial contamination.

4. What causes an older female client's hair to turn gray?

• A. ''A loss of melanin occurs in the normal aging process.''
• B. ''The number of sweat glands and blood vessels decreases in the normal aging process.''
• C. ''The skin on the scalp becomes thin, causing moisture to escape.''
• D. ''It is caused by hereditary factors.''

Correct answer: A

Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.

5. The nurse is caring for a female client who has recently been diagnosed with cancer and will soon begin chemotherapy. Which of these statements would require additional follow-up and education?

• A. I will be most susceptible to an infection between 7 and 12 days after chemotherapy.
• B. I should try to get my annual teeth cleaning in before beginning chemotherapy.
• C. I should wait until all my hair falls out to purchase a wig.
• D. I should try to drink 8-10 glasses of water a day.

Correct answer: C

Rationale: This client is at risk for altered body image due to chemotherapy-induced hair loss. A wig can assist in coping with this change. It is advisable for the client to shop for a wig before hair loss occurs to better match color and style. Waiting until all hair falls out may lead to stress and limited options in finding a suitable wig. Choices A, B, and D are accurate. Understanding the timing of susceptibility to infection, maintaining oral health before chemotherapy, and staying hydrated are important aspects of care during chemotherapy. Therefore, the statement 'I should wait until all my hair falls out to purchase a wig' requires additional follow-up and education.
