Correct Answer: A

Rationale: Proper latch technique is the most important nursing intervention to alleviate nipple soreness in a breastfeeding client. When a baby latches on correctly, it helps prevent nipple trauma and soreness. Educating the client on how to achieve a proper latch, such as ensuring the baby's mouth covers both the nipple and areola, can significantly reduce discomfort during feedings. Improving the latch can also enhance milk transfer, leading to better breastfeeding outcomes for both the mother and baby. While lanolin cream (choice C) can provide some relief for sore nipples, addressing the root cause by correcting the latch is crucial for long-term comfort and successful breastfeeding. Using nipple shields (choice B) or encouraging the use of breast pumps (choice D) should not be the first line of intervention when addressing sore nipples, as they do not address the underlying issue of latch technique.

Correct Answer: B

Rationale: The correct answer is to avoid sharing items used by the infected person in order to prevent the spread of Scabies infestation to other residents in the community. Scabies is a highly contagious skin infestation caused by the Sarcoptes scabiei mite, and it can easily spread through direct skin-to-skin contact or by sharing personal items such as clothing, towels, and bedding. By advising the family to avoid sharing items used by the infected person, Nurse Emma is helping to prevent the transmission of the mites to others in the community. Boiling utensils, taking excessive baths, or wearing masks and shields are not necessary preventive measures for scabies infestation.

Correct Answer: B

Rationale: Elevating the head of the bed to improve respiratory mechanics is the most appropriate intervention for managing paroxysmal nocturnal dyspnea in a patient with end-stage heart failure. By keeping the head of the bed elevated, gravity helps reduce the pooling of fluid in the lungs, making it easier for the patient to breathe and reducing dyspnea. This strategy can help improve oxygenation and decrease the sensation of breathlessness, providing relief for the patient. Administering diuretic medications (Option A) can also be beneficial to reduce fluid overload, although positioning remains a key intervention. Encouraging the patient to sleep in a reclined position (Option C) can help alleviate symptoms, but specifically elevating the head of the bed is a more targeted approach. Referring the patient to a sleep specialist (Option D) may not be necessary at this time, as the primary concern is managing the acute symptom of paroxysmal nocturnal dyspnea

Correct Answer: A

Rationale: The described presentation of a painless, slowly enlarging mass in the right neck just above the clavicle, along with the cytology findings of clusters of polygonal cells with clear cytoplasm and centrally located nuclei, is classic for parathyroid adenoma. Parathyroid adenomas are benign tumors arising from one of the parathyroid glands, which are typically located in the neck region close to the thyroid gland. The clear cytoplasm and centrally located nuclei of the cells are characteristic histological features of parathyroid adenomas. This condition can often lead to hyperparathyroidism, characterized by increased levels of parathyroid hormone (PTH) and hypercalcemia. Treatment involves surgical removal of the adenoma.

Correct Answer: B

Rationale: The diagnostic test that could be useful in confirming the diagnosis of Dengue Fever is the ELISA test. ELISA stands for Enzyme-Linked Immunosorbent Assay. This test detects the presence of dengue virus-specific antibodies (IgM and IgG) in the blood of an individual suspected to have dengue fever. Elevated levels of these antibodies indicate a recent or ongoing dengue virus infection. ELISA is a standard and reliable test used in diagnosing dengue fever, along with clinical symptoms and other laboratory tests.
