Nursing Elites

1. An infant, age 6 months, has six teeth. The nurse should recognize that this is what?

• A. Normal tooth eruption
• B. Delayed tooth eruption
• C. Unusual and dangerous
• D. Earlier than expected tooth eruption

Correct answer: D

Rationale: Having six teeth at 6 months is earlier than the typical tooth eruption schedule, but it is not unusual or dangerous. It is within the range of normal variations in infant development.

2. 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.

3. The clinic nurse is instructing parents about caring for a toddler with ascariasis (common roundworm). Which statement made by the parents indicates a need for further teaching?

• A. We will wash our hands often, especially after diaper changes
• B. We know that roundworm can be transmitted from person to person
• C. We will be sure to continue the nitazoxanide (Alinia) orally for 3 days
• D. We will bring a stool sample to the clinic for examination in 2 weeks

Correct answer: B

Rationale: Roundworm (ascariasis) is typically transmitted through ingestion of contaminated soil, not directly from person to person. This statement indicates a misunderstanding requiring clarification.

4. At which age should the nurse expect an infant to begin smiling in response to pleasurable stimuli?

• A. 1 month
• B. 2 months
• C. 3 months
• D. 4 months

Correct answer: B

Rationale: Infants typically begin to smile in response to pleasurable stimuli by 2 months, which is an early sign of social interaction and emotional development.

5. Baby M is 5 months old. You notice that she now has the ability to grasp objects between her fingers and opposing thumb. This is known as:

• A. Parachute reflex
• B. Grasp reflex
• C. Pincer grasp
• D. Prehension

Correct answer: C

Rationale: The correct answer is C: Pincer grasp. The pincer grasp is the ability to hold objects between the thumb and another finger, typically developed around 9-12 months. At 5 months, it is early for a pincer grasp to fully develop, but the beginning of this skill can be seen as early as 5 months. Choices A and B are incorrect as the parachute reflex is a protective response to falling and the grasp reflex is an automatic response to touch. Choice D, prehension, is a general term for the act of grasping or holding objects, but it does not specifically refer to holding objects between the thumb and fingers like the pincer grasp does.
