Nursing Elites

1. Which vitamin deficiency is most associated with night blindness?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.

2. A client tells the PN that she has a family history of cancer and has increased the amount of dairy products in her diet to reduce her risk of getting cancer. How should the PN respond?

• A. Encourage the client to get plenty of exercise in addition to the dietary change
• B. Provide written information about the seven warning signs of cancer
• C. Remind the client to ensure that the dairy products are fortified with Vitamin D
• D. Suggest that an increase in fruits and vegetables is more beneficial

Correct answer: D

Rationale: Increasing fruits and vegetables in the diet is more beneficial in reducing cancer risk due to their high levels of antioxidants and fiber, which help protect against cancer. While exercise is important for overall health, in this context, focusing on fruits and vegetables is more relevant to reducing cancer risk than exercise alone. Providing information about cancer warning signs is not directly addressing the client's dietary choice. While Vitamin D is essential for various health aspects, the primary focus here should be on a diet rich in fruits and vegetables for cancer risk reduction.

3. The nurse and UAP enter a client's room and find the client lying on the bed. The nurse determines that the client is unresponsive. Which instruction should the nurse give the UAP first?

• A. Obtain emergency help
• B. Feel for a carotid pulse
• C. Bring a glucometer to the room
• D. Check the blood pressure

Correct answer: A

Rationale: The correct answer is to instruct the UAP to obtain emergency help first. In a situation where a client is unresponsive, the priority is to ensure that help is summoned promptly. This allows for the availability of necessary resources and assistance for resuscitation or other emergency interventions. Feeling for a carotid pulse or checking the blood pressure can be important assessments but are secondary to obtaining immediate help. Bringing a glucometer to the room, while relevant in certain situations, is not the priority when the client's unresponsiveness indicates a need for urgent intervention.

4. The nurse is providing care for a client with type 1 diabetes mellitus who is receiving NPH insulin. The nurse notices that the client's evening glucose levels are consistently above 260 mg/dl. What does this indicate?

• A. States that her feet are constantly cold and feel numb
• B. A wound on the ankle that starts to drain and becomes painful
• C. Consecutive evening serum glucose greater than 260 mg/dl
• D. Reports nausea in the morning but still able to eat breakfast

Correct answer: C

Rationale: High evening glucose levels suggest that the current insulin dosage may be inadequate to control the client's blood sugar levels effectively. This indicates poor glycemic control and the need for a possible adjustment in the insulin regimen. Option A describes symptoms of peripheral neuropathy, which are not directly related to the elevated glucose levels but may be a long-term complication of diabetes. Option B describes a wound infection, which is not directly related to the client's high glucose levels. Option D mentions morning nausea, which could be due to various causes and is not directly related to the high evening glucose levels.

5. Which condition is commonly screened for in newborns using the Guthrie test?

• A. Phenylketonuria (PKU)
• B. Cystic fibrosis
• C. Down syndrome
• D. Sickle cell anemia

Correct answer: A

Rationale: The Guthrie test is specifically designed to screen newborns for phenylketonuria (PKU), a metabolic disorder that can lead to intellectual disability if left untreated. Phenylketonuria is caused by the deficiency of an enzyme required to metabolize the amino acid phenylalanine. Screening for PKU in newborns is crucial as early diagnosis and intervention can prevent the severe consequences associated with the condition. Choices B, C, and D are incorrect as the Guthrie test is not used to screen for cystic fibrosis, Down syndrome, or sickle cell anemia.
