Correct Answer: D

Rationale: Immunotherapy, also known as allergy shots, is a form of treatment that can help reduce symptoms for individuals with severe allergies to substances such as pollen, dust mites, or pet dander. This treatment involves exposing the patient to small, increasing doses of the allergen over time to help the immune system gradually build up a tolerance. Patients with severe allergies to grass and tree pollen would most likely benefit from immunotherapy as it can help reduce their allergy symptoms and improve their quality of life. On the other hand, individuals with anaphylactic reactions to insect stings (Choice A), allergies to eggs and dairy (Choice B), or a positive tuberculin skin test (Choice C) are not typically candidates for immunotherapy as their conditions are not related to the type of allergies that are commonly treated with this method.

Correct Answer: A

Rationale: Rho(D) immune globulin (RhoGAM) needs to be administered within 72 hours postpartum to Rh-negative patients who have given birth to Rh-positive infants to prevent Rh sensitization. The patient delivered at 6:30 AM on January 10, so the RhoGAM should be administered prior to that time on January 13, which is 72 hours postpartum. Therefore, the correct choice is A. 6:30 AM on January 10.

Correct Answer: A

Rationale: Morbid obesity is a risk factor for developing a condition known as intertrigo, which is inflammation of the skin folds. In this case, the skin folds of the vulva are affected, leading to vulvitis. The warm and moist environment between the skin folds in obese individuals can promote the growth of microorganisms and the development of inflammation. This can result in symptoms such as tenderness and redness in the vulva. Since testing did not reveal the presence of any known causative microorganism, the patient's morbid obesity may be the underlying factor contributing to the symptoms of vulvitis. Treating the intertrigo and addressing the underlying obesity may help alleviate the symptoms.

Correct Answer: C

Rationale: The most appropriate action for a patient with H. pylori is to encourage completion of antibiotic therapy. H. pylori is a bacterium that causes peptic ulcers, and treatment involves a combination of antibiotics to eradicate the infection. Antibiotic therapy is crucial in eliminating the bacteria and preventing complications such as recurrent ulcers or stomach cancer. Therefore, the nurse should prioritize ensuring that the patient completes the prescribed course of antibiotics to effectively treat the H. pylori infection.

Correct Answer: D

Rationale: Recurrent episodes of acute otitis media (AOM) can cause fluid accumulation in the middle ear, leading to hearing loss and increased risk of further infections. Insertion of a ventilation tube, also known as a tympanostomy tube, is a common intervention for children with recurrent AOM. This procedure involves placing a tiny tube through the eardrum to allow ventilation and drainage of fluid from the middle ear. Ventilation tubes help equalize pressure, prevent fluid buildup, and reduce the frequency of ear infections. It can improve hearing and decrease the likelihood of future episodes of AOM. Ossiculoplasty, insertion of a cochlear implant, and stapedectomy are not indicated for recurrent AOM.
