Nursing Elites

1. In planning care for a premature infant with respiratory distress syndrome, nursing actions are based on the fact that the most likely cause of this problem stems from the infant's inability to

• A. Stabilize alveolar surface tension
• B. Maintain alveolar surface tension
• C. Promote normal pulmonary blood flow
• D. Regulate intra-cardiac pressure

Correct answer: B

Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.

2. During an admission history, a client tells a nurse that she is under a lot of stress. Which of the following physiological responses should the nurse expect to increase as a result of stress?

• A. Blood glucose - a common stress response.
• B. Intestinal peristalsis - should decrease due to stress.
• C. Peripheral blood vessels diameter - can vary in response to stress.
• D. Urine output - may vary but not a typical stress response.

Correct answer: A

Rationale: The correct answer is A. Stress typically increases blood glucose levels due to the release of stress hormones like cortisol and adrenaline. Elevated blood glucose helps provide energy for the body to cope with the stressful situation. Choice B is incorrect because intestinal peristalsis, the movement of the intestines, is more likely to decrease under stress due to the 'fight or flight' response. Choice C is incorrect as peripheral blood vessels' diameter may vary in response to stress, with both constriction and dilation possible. Choice D is incorrect as urine output may increase or decrease depending on individual differences and the specific stress response, but it is not a typical or direct physiological response to stress.

3. Which statement by the mother indicates that the mother understands safety precautions with her four-month-old infant and her 4-year-old child?

• A. I secure the infant car seat in the back seat facing backwards.
• B. I place my infant in the middle of the living room floor on a blanket to play with my 4-year-old while I make supper in the kitchen.
• C. My sleeping baby looks adorable in the crib with the little buttocks up in the air while the four-year-old naps on the sofa.
• D. I have the 4-year-old hold and help feed the four-month-old a bottle in the kitchen while I make supper.

Correct answer: D

Rationale: Choice D is the correct answer because having the 4-year-old help feed the four-month-old a bottle in the kitchen while the mother makes supper shows supervision of the infant by the older child in a safe environment. This choice indicates that the mother understands safety precautions by involving the older child in a caregiving task under her supervision. Choices A, B, and C are incorrect because they involve unsafe practices such as placing the infant on the floor unsupervised, positioning the infant car seat in the front seat, and not providing direct supervision of the children during naptimes.

4. Three days following surgery, a male client observes his colostomy for the first time. He becomes quite upset and tells the LPN that it is much bigger than he expected. What is the best response by the nurse?

• A. Reassure the client that he will become accustomed to the stoma's appearance in time.
• B. Instruct the client that the stoma will become smaller when the initial swelling diminishes.
• C. Offer to contact a member of the local ostomy support group to help him with his concerns.
• D. Encourage the client to handle the stoma equipment to gain confidence with the procedure.

Correct answer: B

Rationale: The correct response is to instruct the client that the stoma will become smaller when the initial swelling diminishes. This explanation helps reassure the client about the temporary appearance of the stoma. Choice A is incorrect because simply reassuring the client that he will become accustomed to the stoma's appearance does not address the immediate concern about the stoma size. Choice C is incorrect because offering to contact a support group does not directly address the client's current distress about the stoma size. Choice D is incorrect because encouraging the client to handle stoma equipment does not directly address the client's concern about the stoma size and may not be appropriate at this time.

5. A client has a sodium level of 125. What findings should the nurse expect?

• A. Abdominal cramping
• B. Elevated blood pressure
• C. Decreased heart rate
• D. Increased thirst

Correct answer: A

Rationale: Low sodium levels (hyponatremia) often present with various symptoms, including abdominal cramping. Abdominal cramping is a common manifestation of hyponatremia due to the altered electrolyte balance. Option B ('Elevated blood pressure') is incorrect because low sodium levels typically lead to decreased blood pressure, not elevated. Option C ('Decreased heart rate') is incorrect as low sodium levels are more likely to cause an irregular heart rate rather than a decreased heart rate. Option D ('Increased thirst') is incorrect because excessive thirst is more commonly associated with high sodium levels (hypernatremia) rather than low sodium levels.
