Correct Answer: C

Rationale: The pharmacist is legally responsible in this situation because they are the healthcare professional authorized to dispense medications according to the physician's order. In this case, the physician ordered a dose higher than the maximum safe dose recommended based on the infant's current weight. While the nurse administers the medication, the pharmacist has the responsibility to ensure that the correct dose is dispensed and to alert the physician if there is a discrepancy in the order. If the pharmacist dispensed the incorrect dose without verifying with the physician, they would bear legal responsibility for any adverse effects resulting from the medication error.

Correct Answer: A

Rationale: Providing education on techniques to enhance milk production and supply should be prioritized to address the client's concerns about milk supply and meeting the baby's nutritional needs. By educating the client on proper breastfeeding techniques, frequent nursing sessions, skin-to-skin contact, and the importance of staying hydrated, the nurse can help promote successful breastfeeding and potentially increase milk production. Supplemental formula feedings are not the first line of intervention, as breastfeeding should be encouraged, especially for a preterm infant who may benefit significantly from breast milk. Encouraging the client to avoid breastfeeding until the infant reaches full term is not appropriate, as breastfeeding can still be beneficial for a preterm infant. Referring the client to a dietitian for specialized nutritional support may be beneficial, but addressing milk supply concerns through education should be prioritized initially to support breastfeeding success.

Correct Answer: B

Rationale: The epigastrium is the upper middle region of the abdomen, lying above the umbilical region and between the hypochondriac regions. It contains several organs including the duodenum, pancreas, portion of the liver, and the pyloric end of the stomach. The duodenum is the first part of the small intestine, the pancreas is a crucial organ for digestion and hormone regulation, the liver aids in digestion and detoxification, and the pyloric end of the stomach connects the stomach to the small intestine for further digestion and absorption of nutrients. These organs are typically assessed and examined when focusing on the epigastrium during a physical examination.

Correct Answer: C

Rationale: The initial teaching given to a patient with ALS and her family should focus on explaining the disease process, the expected course, and prognosis. Providing this information early on can help the patient and her family understand what to expect, make informed decisions about care and treatment, and prepare emotionally for the challenges ahead. It is important to establish open communication and provide support from the beginning to help the patient and her family cope with the diagnosis and navigate the journey with ALS. While referral to support groups, prevention of complications, and prevention of depression are all important aspects of care for ALS patients, understanding the disease process and prognosis is fundamental to setting realistic expectations and planning for the future.

Correct Answer: C

Rationale: Mast cells are primarily responsible for mediating allergic responses such as severe allergies. When an allergen triggers the immune response, mast cells release histamine, leukotrienes, and other inflammatory mediators. These substances cause symptoms such as difficulty breathing, hives, and swelling. Basophils also release histamine, but mast cells are more abundant in tissues and play a significant role in allergic reactions. Eosinophils are involved in allergic reactions but are more focused on combating parasitic infections. Neutrophils are not typically involved in allergic responses but play a key role in combating bacterial infections.
