Correct Answer: D

Rationale: The correct answer is D because over-the-counter nasal sprays, especially those containing decongestants, can lead to rebound swelling when used for an extended period. Rebound swelling occurs when the nasal passages become more congested after the effects of the medication wear off. This can result in a cycle of dependency on the nasal spray to alleviate symptoms, leading to worsening congestion over time. It is important for the nurse to educate the patient about this potential risk and suggest alternative treatment options to address her allergies effectively without causing rebound swelling.



Choices A, B, and C are incorrect because:
A: Incorrect, as not all over-the-counter nasal sprays carry a risk of addiction.
B: Incorrect, as switching to another brand may not address the underlying issue of rebound swelling.
C: Incorrect, as continuous use of the nasal spray without addressing rebound swelling can exacerbate the problem.

Correct Answer: B

Rationale: The correct answer is B: When the patient first noticed the lesion. This information is crucial for determining the duration of the ulceration, aiding in diagnosing potential causes like trauma or infections. Nutritional status (
Choice
A) may not be directly related to the specific lesion. Whether the patient has had a recent cold (
Choice
C) is less relevant unless there are other symptoms present. Exposure to sick animals (
Choice
D) is not pertinent to the mouth ulceration.
Therefore, obtaining information on when the patient first noticed the lesion is the most important for proper assessment and treatment planning.

Correct Answer: B

Rationale: The correct answer is B. When using an otoscope to assess the nasal cavity, it is crucial to avoid touching the nasal septum with the speculum to prevent discomfort or injury to the patient.
Touching the nasal septum can cause pain and potential damage.

Incorrect

Choices:
A: Inserting the speculum at least 3 cm into the vestibule is not necessary and may cause discomfort or injury to the patient.
C: Displacing the nose to the side being examined is not required and may not provide any additional benefit during the assessment.
D: Keeping the speculum tip medial to avoid touching the floor of the nares is not as critical as avoiding contact with the nasal septum, which is more sensitive and can be easily injured.

Correct Answer: C

Rationale: The correct answer is C because the normal eardrum of a newborn can appear thick and opaque due to the presence of vernix or desquamated epithelium. Immobility of the drum (
Choice
A) is not a normal finding in a newborn and could indicate a problem. An "injected" membrane (
Choice
B) would suggest inflammation or infection, not necessarily infection. The appearance of the membrane in a newborn is not identical to that of an adult (
Choice
D) as it may have a different color, thickness, or opacity due to developmental differences.

Correct Answer: B

Rationale:
Correct Answer: B


Rationale:
1. Rubbing alcohol or 2% acetic acid eardrops help to maintain the pH balance in the ear canal, making it less conducive to bacterial growth.
2. These eardrops also help to dry out excess moisture, reducing the risk of otitis externa.
3. By using these eardrops after every swim, the student can prevent the recurrence of otitis externa.

Summary of other choices:
A: Using a cotton-tipped swab can push wax deeper into the ear canal, increasing the risk of infection.
C: Irrigating the ears can introduce water into the ear canal, potentially worsening the condition.
D: Mineral oil and hydrogen peroxide can be harsh on the delicate skin of the ear canal, causing irritation.
