The physician orders local application of epinephrine 1:1000 solution to treat a nosebleed. The patient asks how this will help. Which of the ff. responses by the nurse is best?

Correct Answer: D

Rationale: Epinephrine is a vasoconstrictor, which means it causes blood vessels to narrow. When applied locally to the site of a nosebleed, epinephrine constricts the blood vessels in the nose, slowing down and stopping the bleeding. By constricting the blood vessels, epinephrine helps to reduce the blood flow to the area, allowing a clot to form and stop the bleeding. This is why option D, "It will constrict your vessels and slow down the bleeding," is the best response by the nurse to explain how epinephrine will help treat a nosebleed.

Correct Answer: C

Rationale: Trigeminal neuralgia is a condition characterized by sudden and severe facial pain caused by irritation or damage to the trigeminal nerve. Trigeminal neuralgia pain is often triggered by certain activities that stimulate the nerve, such as eating, talking, or brushing teeth. The act of chewing and ingesting food can put pressure on the trigeminal nerve, leading to increased pain for individuals suffering from trigeminal neuralgia. Therefore, eating is most likely to aggravate the pain in a 19-year-old student with trigeminal neuralgia.

Correct Answer: C

Rationale: Ribavirin (Virazole) is an antiviral medication used to treat severe cases of respiratory syncytial virus (RSV) infection in infants, young children, and immunocompromised individuals. RSV is a common virus that causes respiratory infections in people of all ages, but it can be particularly severe in young children and individuals with weakened immune systems. Ribavirin works by preventing the virus from replicating and spreading further in the body, helping to reduce the severity and duration of RSV infection. It is not used to treat cystic fibrosis, otitis media, or bronchitis.

Correct Answer: D

Rationale: Vitamin D is essential for the absorption of calcium in the body. Without sufficient vitamin D, the absorption of calcium from the diet is impaired, leading to potential issues with calcium deficiency. Vitamin A, B, and C do not have a direct role in the absorption of calcium. Vitamin D helps regulate the amount of calcium and phosphate in the body, which are necessary for bone health, muscle function, and other important processes. Therefore, a lack of Vitamin D can contribute to weakened bones and potential health problems related to calcium deficiency.

Correct Answer: D

Rationale: A hemolytic reaction is the most likely problem associated with blood transfusion. A hemolytic reaction occurs when the body's immune system attacks the transfused blood, leading to the destruction of red blood cells. This reaction can cause serious complications, including kidney damage, shock, and even death. It is crucial for healthcare providers to carefully match blood types and perform compatibility testing before administering a blood transfusion to minimize the risk of a hemolytic reaction. Serum hepatitis, pulmonary edema, and allergic responses are potential complications of blood transfusions, but hemolytic reactions pose the most immediate and severe threat to the patient's health.
