1. What type of dehydration occurs when the electrolyte deficit exceeds the water deficit?

Correct answer: B

Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.

2. Chemicals, agents, or factors that cause physical defects in the developing embryo and are most harmful during organogenesis are:

Correct answer: A

Rationale: Teratogens are substances that can cause congenital abnormalities, especially during the first trimester when organogenesis occurs. Choice A, Teratogens, is the correct answer as it specifically refers to substances that cause physical defects in the developing embryo. Choices B, Heterozygous, C, Inborn errors, and D, Multifactorial, are incorrect as they do not directly relate to substances that cause physical defects in embryos during organogenesis.

3. An appropriate method for administering oral medications that are bitter to an infant or small child should be to mix them with which?

Correct answer: C

Rationale: Mixing bitter medication with a small amount of something sweet, like jam, can mask the taste effectively without diluting the medication too much. Mixing with milk or formula is not recommended as the child may refuse future feedings, and carbonated beverages are not suitable for infants.

4. Which drug is usually the best choice for patient-controlled analgesia (PCA) for a child in the immediate postoperative period?

Correct answer: B

Rationale: Morphine is the drug of choice for PCA in children because of its efficacy, safety profile, and rapid onset of action for pain management.

5. A hospitalized child with minimal change nephrotic syndrome is receiving high doses of prednisone. What nursing goal is appropriate for this child?

Correct answer: C

Rationale: Prednisone, an immunosuppressant, increases the child's susceptibility to infections, making infection prevention a critical nursing goal. Detecting edema and stimulating appetite are important but secondary to preventing potentially life-threatening infections.
