Nursing Elites

1. Which of the following is reflected in an ECG due to hypokalemia?

• A. Tall T waves and Pathologic Q wave
• B. Widening QRS Complex and U wave
• C. None of the above
• D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

2. Clients may benefit from slightly higher fat intakes than are normally recommended if they have:

• A. congestive heart failure
• B. cerebrovascular accident
• C. peripheral vascular disease
• D. chronic obstructive pulmonary disease

Correct answer: D

Rationale: In chronic obstructive pulmonary disease (COPD), higher fat intake can be beneficial because it provides more calories with less respiratory burden compared to carbohydrates. Choices A, B, and C are incorrect because congestive heart failure, cerebrovascular accident, and peripheral vascular disease do not specifically benefit from higher fat intakes as in COPD.

3. Inadequate intake of vitamin A occurs in lower socioeconomic groups due to a lack of resources to purchase and consume vegetables and fruits.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. Inadequate intake of vitamin A in lower socioeconomic groups is due to a lack of resources to purchase and consume vegetables and fruits. This is supported by the fact that the average intake in the United States meets the Recommended Dietary Allowance (RDA) for vitamin A intake, except in lower socioeconomic groups. These individuals often lack the financial means to buy, prepare, and eat a variety of fruits and vegetables, leading to deficiencies. It's important to note that because vitamin A can be stored in the liver, most adults have sufficient quantities to maintain health. Choices B, C, and D are incorrect because the statement and reason are both accurate and logically connected, as the lack of resources directly impacts the ability to obtain necessary sources of vitamin A.

4. Ms. ANA had a car accident where he lost her boyfriend. As a result, she became passive and submissive. The nurse knows that the type of crisis Ms. ANA is experiencing is:

• A. Developmental crisis
• B. Maturational crisis
• C. Situational crisis
• D. Social Crisis

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. Of the following neurotransmitters, which demonstrates inhibitory action, helps control mood and sleep, and inhibits pain pathways?

• A. Serotonin
• B. Enkephalin
• C. Norepinephrine
• D. Acetylcholine

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
