Nursing Elites

1. 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.

2. Melena, the passage of black, tarry stools, suggests bleeding from which source?

• A. The perianal or rectal area
• B. The upper gastrointestinal (GI) tract
• C. The lower GI tract
• D. Hemorrhoids or anal fissures

Correct answer: B

Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.

3. What is the appropriate site to administer an intramuscular (IM) vaccine to a newborn?

• A. The dorsal gluteal muscle
• B. The vastus lateralis muscle
• C. The ventral gluteal muscle
• D. The biceps muscle

Correct answer: B

Rationale: The correct site to administer an intramuscular (IM) vaccine to a newborn is the vastus lateralis muscle. For newborns, the vastus lateralis is preferred over the dorsogluteal site because the dorsogluteal site has been associated with low antibody seroconversion rates, indicating a reduced immune response. The vastus lateralis is also recommended for IM injections in newborns, while the deltoid muscle is preferred for older infants and children. The ventral gluteal muscle and the biceps muscle are not appropriate sites for IM injections. Therefore, choice B is the correct answer.

4. With the National Center for Health Statistics criteria, which body mass index (BMI)-for-age percentiles should indicate the patient is at risk for being overweight?

• A. 10th percentile
• B. 75th percentile
• C. 85th percentile
• D. 95th percentile

Correct answer: C

Rationale: A BMI-for-age at the 85th percentile indicates a child is at risk for being overweight, according to the National Center for Health Statistics criteria.

5. According to Maslow’s hierarchy, what is the most advanced need provided by the home environment?

• A. Love
• B. Self-actualization
• C. Esteem
• D. Physiological

Correct answer: B

Rationale: The correct answer is B, self-actualization. Self-actualization is the highest level in Maslow's hierarchy of needs, representing the realization of one's full potential. While love is an essential need, self-actualization builds upon the fulfillment of basic needs like safety and love. Esteem needs relate to feelings of accomplishment and recognition, which come before self-actualization. Physiological needs such as food, water, and shelter are the most basic needs at the bottom of the hierarchy.
