Nursing Elites

1. A community health nurse is conducting a class on what to expect during pregnancy. What instruction should the nurse include on weight gain?

• A. Failure to obtain the required weight gain during pregnancy will increase the risk of preterm birth.
• B. An obese client should not gain as much weight as a client with a normal body mass index.
• C. A client with a normal body mass index should plan on gaining 50 pounds.
• D. Clients do not need to eat for two when they are pregnant.

Correct answer: A

Rationale: Adequate weight gain during pregnancy is essential as failure to obtain the required weight gain can increase the risk of preterm birth. Choice B is incorrect because it is important for obese clients to gain an appropriate amount of weight during pregnancy, not the same as those with a normal body mass index. Choice C is incorrect as gaining 50 pounds for a client with a normal body mass index is excessive. Choice D is incorrect as the common saying 'eating for two' during pregnancy is a misconception; pregnant individuals do not need to double their caloric intake.

2. Onset frequently occurs after the age of 40.

• A. Type 1 Diabetes
• B. Type 2 Diabetes
• C.
• D.

Correct answer: B

Rationale: The correct answer is B, Type 2 Diabetes. Type 2 Diabetes commonly presents with an onset after the age of 40, although it is now also seen in younger individuals due to lifestyle factors such as poor diet and lack of exercise. Type 1 Diabetes, on the other hand, typically develops in childhood or adolescence and is not associated with age over 40. Choices C and D are left blank as they are not relevant to the question.

3. A healthcare provider is assessing a client who has a stage III pressure ulcer that is healing poorly. The provider should identify that which of the following vitamin deficiencies increases the client’s risk for delayed wound healing?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin E
• D. Vitamin B6

Correct answer: A

Rationale: Corrected Rationale: Vitamin C deficiency can impair collagen synthesis and delay wound healing, making it crucial for recovery from pressure ulcers. Incorrect Rationales: - Vitamin D deficiency is associated with bone health, not specifically wound healing. - Vitamin E deficiency can lead to neurological and immune system issues but is not directly linked to delayed wound healing. - Vitamin B6 deficiency can cause skin rashes and neurological symptoms but is not a primary factor in delayed wound healing.

4. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

5. Which of the following terms describes the amount of blood ejected per heartbeat?

• A. Stroke volume
• B. Cardiac output
• C. Ejection fraction
• D. Afterload

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.
