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

A. "The client’s degree of nausea."

The client's degree of nausea is a side effect of chemotherapy, but it is not a major obstacle to successful chemotherapy in the broader sense. Nausea can often be managed with antiemetic medications, and it is generally considered a manageable aspect of chemotherapy care.

B. "The patient’s reluctance about the doses administered."

Patient compliance and acceptance of the prescribed treatment are important factors in the success of chemotherapy. However, while patient reluctance can be a challenge, it is not considered a major obstacle to chemotherapy as there are strategies and interventions to address issues related to patient understanding, fears, or concerns.

C. "The toxicity of anticancer drugs to normal tissues."

This is the correct answer. The toxicity of anticancer drugs to normal tissues is a major obstacle in chemotherapy. While the drugs aim to kill rapidly dividing cancer cells, they can also affect healthy cells, leading to side effects and complications. Striking a balance between effective cancer treatment and minimizing harm to normal tissues is a key challenge in chemotherapy.

D. "The difficulty of maintaining venous access."

Maintaining venous access can be a logistical challenge in chemotherapy, but it is not considered a major obstacle to successful treatment. While it is important for delivering chemotherapy drugs, there are various methods and technologies to address issues related to venous access, such as the use of central venous catheters or ports.

A. Tiotropium bromide (Spiriva)

Tiotropium bromide is a long-acting anticholinergic bronchodilator used for maintenance therapy in conditions like chronic obstructive pulmonary disease (COPD). It is not indicated for the immediate relief of acute asthma symptoms.

B. Montelukast (Singulair)

Montelukast is a leukotriene receptor antagonist used for maintenance therapy in asthma. It is not a rescue medication and does not provide immediate relief during an acute asthma attack.

C. Albuterol (Proventil)

In the case of an acute asthma attack, the nurse should prepare to administer a short-acting bronchodilator. Albuterol (Proventil) is a short-acting beta-agonist bronchodilator that provides rapid relief of bronchoconstriction and acute symptoms during an asthma attack.

D. Acetylcysteine (Mucomyst)

Acetylcysteine is a mucolytic agent used to help loosen and thin mucus in the airways. It is not indicated for the immediate relief of bronchoconstriction during an acute asthma attack.
