Nursing Elites

1. The nurse is evaluating research studies according to the GRADE criteria and has determined the quality of evidence on the subject is moderate. Which type of evidence does this determination indicate?

• A. Strong evidence from unbiased observational studies
• B. Evidence from randomized clinical trials showed inconsistent results
• C. Consistent evidence from well-performed randomized clinical trials
• D. Evidence for at least one critical outcome from randomized clinical trials had serious flaws

Correct answer: B

Rationale: Moderate evidence typically indicates that results from randomized clinical trials were inconsistent, highlighting the need for further research to confirm findings.

2. Parents of a child who will need hemodialysis ask the nurse, What are the advantages of a fistula over a graft or external access device for hemodialysis? (Select all that apply.)

• A. It is ready to be used immediately.
• B. All below
• C. There is less restriction of activity with a fistula.
• D. It produces dilation and thickening of the superficial vessels.

Correct answer: A

Rationale: A fistula typically has fewer complications, allows for greater freedom of movement, and involves natural vessel changes that improve dialysis efficiency. However, it is not ready for immediate use, which is why it may take weeks to mature before it can be used.

3. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

4. What is often the initial sign of acute rheumatic fever in children?

• A. Polyarthritis
• B. Carditis
• C. Erythema marginatum
• D. Sydenham chorea

Correct answer: A

Rationale: Polyarthritis is indeed frequently the initial sign of acute rheumatic fever in children. It presents as joint pain, swelling, and redness. Carditis (inflammation of the heart), Erythema marginatum (a skin rash), and Sydenham chorea (involuntary muscle movements) are typically seen in the later stages of acute rheumatic fever and not as the initial sign.

5. What is typically the first sign of puberty in females?

• A. Breast development
• B. Menarche
• C. Pubic hair growth
• D. Axillary hair growth

Correct answer: A

Rationale: The correct answer is A: Breast development (thelarche) is usually the first sign of puberty in females, typically beginning between ages 8 and 13. This marks the start of puberty, followed by pubic hair growth, a growth spurt, and eventually menarche (the onset of menstruation). Pubic hair growth and axillary hair growth usually follow breast development in the sequence of pubertal changes. Therefore, the first noticeable change indicating the onset of puberty in females is the development of breast buds.
