A client asks the nurse about a prescription for the antihistamine, diphenhydramine (Benadryl). The nurse should teach the client that this medication is contraindicated in clients who have a history of which condition?

Choice A Reason:

Cranial nerve V is the trigeminal nerve, which has both motor and sensory functions:Motor function: The nurse can assess this by asking the client to clench their teeth while palpating the masseter and temporalis muscles for strength.Sensory function: The nurse can assess this by lightly touching the client's face in different areas (forehead, cheeks, and jaw) with a cotton ball or sharp/dull object to check for sensation.

Choice B Reason:

Asking the client to identify scented aromas is a method used to assess cranial nerve I (Olfactory), not cranial nerve V. Cranial nerve V (Trigeminal) is assessed by testing facial sensation and motor functions such as chewing.

Choice C Reason:

Asking the client to read a Snellen chart is a method used to assess cranial nerve II (Optic), which is responsible for vision. This method does not assess cranial nerve V

Choice D Reason:

Asking the client to raise his eyebrows is a method used to assess cranial nerve VII (Facial), which controls facial expressions. This method is not used to assess cranial nerve V.

Choice A Reason:

Urinary tract infections (UTIs) are typically caused by bacteria entering the urinary tract. While strict bed rest can increase the risk of UTIs due to factors like catheter use and reduced mobility, the use of an incentive spirometer does not directly prevent UTIs. Instead, preventing UTIs involves maintaining good hygiene, ensuring adequate fluid intake, and, if necessary, using catheters properly.

Choice B Reason:

Deep vein thrombosis (DVT) is a condition where blood clots form in the deep veins, usually in the legs. This can occur due to prolonged immobility, such as strict bed rest after surgery. Preventing DVT involves measures like using compression stockings, administering anticoagulant medications, and encouraging leg exercises. An incentive spirometer, which is used to improve lung function, does not directly prevent DVT.

Choice C Reason:

Constipation is a common issue for patients on bed rest due to reduced physical activity and changes in diet. Preventing constipation involves ensuring adequate hydration, providing a high-fiber diet, and encouraging as much physical activity as possible. The use of an incentive spirometer, which focuses on respiratory function, does not directly address constipation.

Choice D Reason:

Atelectasis is a condition where the alveoli in the lungs collapse, leading to reduced or absent breath sounds in the affected areas. This is a common postoperative complication, especially in patients on strict bed rest, due to shallow breathing and reduced lung expansion. The use of an incentive spirometer encourages deep breathing and helps to keep the alveoli open, thereby preventing atelectasis. This is why the incentive spirometer is an essential tool for postoperative respiratory care.
