Before administering diphenhydramine (Benadryl) to a client, it is most important for the nurse to assess for which history?

Hypotension

Allergy to penicillin

Narrow-angle glaucoma

Diabetes insipidus

Answer and Explanation

The Correct Answer is C

A. Hypotension

While diphenhydramine can cause drowsiness and may contribute to orthostatic hypotension, it is not a strict contraindication. However, caution should be exercised in patients with hypotension.

B. Allergy to penicillin

An allergy to penicillin is not directly related to the use of diphenhydramine. Allergies to specific medications, including penicillin, are important to assess but are not a primary concern when administering diphenhydramine.

C. Narrow-angle glaucoma

Diphenhydramine can cause pupil dilation and may worsen narrow-angle glaucoma, leading to increased intraocular pressure. Therefore, it is crucial to assess for a history of narrow-angle glaucoma before administering diphenhydramine. If a patient has a history of this condition, alternative medications or careful monitoring may be necessary.

D. Diabetes insipidus

Diabetes insipidus is not typically a contraindication for diphenhydramine. However, it is essential to consider the overall health status and specific needs of the patient. Diphenhydramine may have anticholinergic effects, and caution is advised in patients with certain medical conditions.

Correct Answer is B

Explanation

A. Relieves nasal congestion

Dornase alfa is not used to relieve nasal congestion. It is specifically designed to address the thick, sticky mucus that can accumulate in the airways of individuals with cystic fibrosis (CF).

B. Decreases thick secretions

This is the correct answer. Dornase alfa is known for its ability to decrease the viscosity of thick secretions in the airways of individuals with CF. By breaking down the DNA within the mucus, it helps to thin and improve the clearance of the mucus.

C. Decreases pain

Dornase alfa is not primarily used to decrease pain. Its main action is related to improving respiratory function by reducing the thickness of mucus, which can help ease breathing difficulties associated with CF.

D. Suppresses cough

Dornase alfa is not used to suppress cough. In fact, it may increase coughing initially as it facilitates the loosening and clearance of mucus from the airways.

A. The inhaled form may cause more side effect than the oral form. B. The inhaled form requires an increased dose. C. The inhaled form will not lead to increased doses. D. The inhaled form has a more immediate onset of action.

Correct Answer is D

Explanation

A. The inhaled form may cause more side effects than the oral form.

The route of administration does not necessarily determine the likelihood of side effects. Both inhaled and oral forms of albuterol can cause side effects, but they may vary in nature.

B. The inhaled form requires an increased dose.

The dose of albuterol may differ between inhaled and oral forms, but it is not accurate to say that the inhaled form always requires an increased dose. The choice of dosage depends on factors such as the severity of symptoms and the patient's response to treatment.

C. The inhaled form will not lead to increased doses.

The need for increased doses depends on the individual patient's response and the severity of symptoms. In some cases, increased doses may be necessary, especially during acute exacerbations.

D. The inhaled form has a more immediate onset of action.

Inhaled albuterol has a quicker onset of action compared to the oral form. When inhaled, the medication reaches the airways directly, leading to rapid bronchodilation and relief of symptoms. This is especially important during acute bronchoconstriction or asthma exacerbations when prompt relief is needed.
