1. When conducting a class for parents about sudden infant death syndrome (SIDS), the nurse instructs the class that the infant should be placed in which position to sleep?
- A. Right side-lying
- B. Left side-lying
- C. Prone
- D. Supine
Correct answer: D
Rationale: The correct answer is D, supine. The American Academy of Pediatrics recommends placing infants on their back, or supine, to sleep as it has been shown to reduce the risk of SIDS. Choices A, B, and C are incorrect because placing infants on their right side, left side, or prone (on their stomach) respectively are not recommended sleeping positions due to the increased risk of SIDS associated with those positions.
2. The mother of a child with acute laryngotracheobronchitis (LTB) asks why her child must be kept NPO. Which response would be the most correct?
- A. The epinephrine given causes nausea and vomiting.
- B. The child is being hydrated with IV fluids.
- C. The child is not hungry.
- D. The child's rapid respirations pose a risk for aspiration.
Correct answer: D
Rationale: The correct answer is D because rapid respirations predispose to aspiration in a child with acute laryngotracheobronchitis. Choice A is incorrect because epinephrine does not directly relate to the need for NPO status. Choice B is incorrect as hydration with IV fluids is not the primary reason for keeping the child NPO. Choice C is incorrect as the child being hungry is not the main concern when keeping a child NPO in this situation.
3. Which nursing intervention promotes achievement of the goal 'optimal mobility' for a client who had a total hip replacement 8 hours ago?
- A. Encourage the client to use an abductor pillow when ambulating.
- B. Teach the client to perform leg exercises in bed.
- C. Assist the client to sit at the edge of the bed.
- D. Assist the client to turn while an abductor pillow is between the legs.
Correct answer: D
Rationale: Assisting the client to turn while an abductor pillow is between the legs is the correct intervention to promote optimal mobility for a client who had a total hip replacement 8 hours ago. Using an abductor pillow helps maintain hip alignment and prevents dislocation, which are crucial considerations in the early postoperative period. Encouraging the client to use an abductor pillow when turning is more beneficial compared to the other options: teaching leg exercises in bed, encouraging the use of a walker when ambulating, or assisting the client to sit at the edge of the bed, as these interventions may not directly address the specific needs of a client after a total hip replacement.
4. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?
- A. They involve antigen-antibody complexes.
- B. They are mediated by T cells and do not involve antibodies.
- C. They result in immediate allergic reactions.
- D. They are the least severe form of hypersensitivity.
Correct answer: B
Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.
5. What most influences the severity of respiratory distress syndrome (RDS)?
- A. Poor cough and gag reflex
- B. The gestational age at birth
- C. Administering high concentrations of oxygen
- D. The sex of the infant
Correct answer: B
Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.
