A nurse is preparing a teaching plan for the parent of a school-age child who has asthma. Which of the following manifestations should the nurse include as an indication of an exacerbation of asthma?

Green zone reading on peak expiratory flow meter

Rhinitis

Axillary temperature of 37.2° C (99° F)

Hacking, nonproductive cough

Answer and Explanation

The Correct Answer is D

A. Green zone reading on peak expiratory flow meter:

A green zone reading on a peak expiratory flow meter indicates that the child's peak expiratory flow rate (PEFR) is within the normal or stable range. This would not typically be indicative of an exacerbation of asthma. In fact, a green zone reading suggests that asthma is well-controlled.

B. Rhinitis:

Rhinitis, or inflammation of the nasal mucosa, is a common symptom in individuals with asthma, but it is not necessarily indicative of an exacerbation of asthma. Rhinitis can occur due to allergic or non-allergic triggers and may be present even when asthma is well-controlled.

C. Axillary temperature of 37.2°C (99°F):

An axillary temperature of 37.2°C (99°F) is within the normal range for body temperature and is not indicative of an exacerbation of asthma. While fever can occur during exacerbations of asthma, it is not a universal symptom and may be absent in some cases.

D. Hacking, nonproductive cough:

This is the correct option. A hacking, nonproductive cough is a common symptom of asthma exacerbation. During an exacerbation, the airways become inflamed and constricted, leading to coughing. The cough may be dry and unproductive, and it is often worse at night or early in the morning.

Correct Answer is B

Explanation

A. "I should place the shoulder harness above the level of my baby's shoulders."

This statement is incorrect. Placing the shoulder harness above the baby's shoulders could lead to improper restraint in the event of a crash. The harness should be positioned at or slightly below the level of the baby's shoulders to provide effective protection.

B. "I should place the car seat rear-facing until my baby is 2 years old."

This statement is correct. The American Academy of Pediatrics recommends that infants and toddlers ride in a rear-facing car seat until they are at least 2 years old or until they reach the maximum height and weight limit specified by the car seat manufacturer. This position provides optimal protection for the baby's head, neck, and spine in the event of a crash.

C. "I will place the retainer clip over my baby's abdomen."

This statement is incorrect. The retainer clip, also known as the chest clip, should be positioned at armpit level to secure the harness straps. Placing it over the baby's abdomen could result in serious injuries in the event of a crash.

D. "I should position my baby at a 30-degree angle in the car seat."

This statement is incorrect. Infants should be positioned at a 45-degree angle in their car seats. This angle helps to keep the baby's airway open and prevents the head from flopping forward, which could restrict breathing. Placing the baby at a 30-degree angle may not provide adequate support and protection.

A. Visual acuity 20/30 bilaterally B. Peripheral vision 70° downward C. Movement of the uncovered eye during a cover test D. Light reflects symmetrically within each pupil during a corneal light reflex test

Correct Answer is C

Explanation

A. Visual acuity 20/30 bilaterally: Visual acuity of 20/30 bilaterally indicates relatively good vision in both eyes, but it does not necessarily indicate strabismus. Strabismus is related to eye alignment rather than visual acuity.

B. Peripheral vision 70° downward: Peripheral vision refers to the ability to see objects outside the direct line of vision. While changes in peripheral vision can occur in various eye conditions, such as glaucoma, it is not specific to strabismus.

C. Movement of the uncovered eye during a cover test: This is the correct option. During a cover test, one eye is covered while the other eye fixates on an object. If the uncovered eye moves to try to align with the covered eye, it may indicate strabismus or a misalignment of the eyes.

D. Light reflects symmetrically within each pupil during a corneal light reflex test: A corneal light reflex test assesses the alignment of the eyes by observing the reflection of light on the corneas. While asymmetry in the corneal light reflex can indicate strabismus, the description provided in this option suggests that the light reflects symmetrically within each pupil, which is a normal finding.
