A patient has an as needed prescription for ondansetron. For which condition would the nurse administer this medication?
Diarrhea
Nausea and vomiting
Incisional pain
Paralytic ileus
The Correct Answer is B
A. Ondansetron is not indicated for treating diarrhea. While nausea can accompany diarrhea, ondansetron specifically targets nausea and vomiting rather than the underlying causes of diarrhea.
B. Ondansetron is primarily used to prevent and treat nausea and vomiting, particularly those associated with chemotherapy, radiation therapy, and postoperative recovery. If a patient is experiencing nausea and vomiting, ondansetron would be the appropriate medication to administer.
C. Ondansetron is not indicated for managing pain. Incisional pain is typically treated with analgesics, not antiemetics. While postoperative patients may experience nausea, ondansetron would not be used solely for pain relief.
D. Paralytic ileus is a condition characterized by the lack of movement in the intestines, leading to a blockage. While nausea and vomiting can occur in this condition, ondansetron is not a treatment for the underlying issue of ileus. The focus would be on managing the ileus and any complications that arise.

Correct Answer is C
Explanation
A. This finding can occur with circulatory issues but is not a classic symptom of a hip fracture itself. A cool extremity may indicate vascular compromise, which is less common immediately after a hip fracture and more concerning for a potential complication, such as compartment syndrome.
B. Similar to cool extremities, absent pedal pulses suggest a significant vascular problem and are not typical for a straightforward hip fracture. While this can indicate serious complications, it is not a common presentation immediately following a hip fracture.
C. Misalignment or deformity of the leg is a classic symptom of a fractured hip. The affected leg may appear shorter and externally rotated. This misalignment is often one of the first observable signs that healthcare providers look for during the assessment.
D. Hypotension can occur due to various reasons, including pain, dehydration, or blood loss, but it is not a direct symptom of a fractured hip. While it could be present in some cases, it is not the most characteristic finding associated with hip fractures.
Correct Answer is A
Explanation
A. The appropriate method for tick removal involves using fine-tipped tweezers to grasp the tick as close to the skin's surface as possible and pulling upward with steady, even pressure. This minimizes the risk of the tick's mouthparts breaking off and remaining in the skin.
B. Using bare fingers can be unsanitary and may cause the tick to release more saliva, potentially increasing the risk of disease transmission. Squeezing the tick can also lead to the release of harmful pathogens into the bloodstream.
C. DEET is an insect repellent that is used to prevent tick bites but should not be applied to a tick that is already embedded. Applying repellent will not assist in tick removal and may cause irritation to the skin.
D. While some people believe that applying mineral oil can cause a tick to detach, this method is not recommended. It may irritate the tick and could increase the likelihood of the tick regurgitating pathogens into the skin, raising the risk of infection.
