Patient Josephine was referred to the physician, routine blood examinations were taken. After reviewing the serum electrolyte. levels an order of isotonic intravenous (IV) infusion was prescribed. Which IV solution should the nurse prepare?

Correct Answer: B

Rationale: The order for isotonic intravenous (IV) infusion indicates that the IV solution should have an osmolarity similar to that of blood serum, which is approximately 0.9 percent sodium chloride solution (normal saline). In the given choices, the closest option to isotonic solution is the 0.45 percent sodium chloride solution. This solution is hypotonic compared to blood serum, making it a suitable choice for isotonic IV infusion to prevent fluid shifts and maintain electrolyte balance in the patient. The other options, such as 5 percent dextrose in water (hypotonic), 10 percent dextrose in water (hypertonic), and 3 percent sodium chloride solution (hypertonic), do not match the requirement for an isotonic IV solution in this case.

Correct Answer: A

Rationale: The statement "all employees are lazy " is not a correct assertion. It is a generalization that is unfair to make about all employees. It is incorrect to assume that all employees are lazy based on the failure of a certain staff member to monitor the fire extinguisher. Making blanket statements like this can lead to further misunderstandings and negativity in the workplace. The focus should be on individual accountability, proper training, and clear communication to ensure that tasks are being diligently carried out.

Correct Answer: C

Rationale: Cryptosporidium parvum is a parasite commonly found in contaminated water sources such as streams or lakes. It causes an infection called cryptosporidiosis, which often presents with symptoms like watery diarrhea, abdominal cramps, and nausea. The oocysts of Cryptosporidium parvum can be identified in stool samples, making it the likely culprit in this scenario. Giardia lamblia, another common waterborne parasite, can also cause similar symptoms but is characterized by trophozoites rather than oocysts in stool samples. Entamoeba histolytica is associated with amoebic dysentery and does not typically present with watery diarrhea. Cyclospora cayetanensis is another parasite causing gastrointestinal symptoms but is not as commonly associated with contaminated water sources as Cryptosporidium parvum.

Correct Answer: B

Rationale: In the case of umbilical cord prolapse, the priority nursing action is to prepare for an immediate cesarean section. Umbilical cord prolapse is a serious obstetric emergency where the umbilical cord slips through the cervix ahead of the presenting part of the fetus. This can lead to compression of the cord, compromising fetal blood flow and oxygenation. Immediate delivery via cesarean section is necessary in order to prevent fetal hypoxia and avoid potential complications such as brain damage or death. Elevating the mother's hips or administering intravenous fluids rapidly may be interventions done in conjunction with preparing for a cesarean section, but the priority remains expedited delivery of the baby. Applying external fetal monitoring is not the most appropriate action in this emergency situation.

Correct Answer: B

Rationale: The most appropriate response from the nurse when a patient expresses frustration with the treatment plan proposed by the healthcare team is to empathize with the patient's frustration and explore their concerns further. It is important to actively listen to the patient, acknowledge their feelings, and address any questions or uncertainties they may have about the treatment plan. By engaging in open communication and demonstrating empathy, the nurse can foster a therapeutic relationship with the patient and work towards finding a solution that is mutually agreeable and beneficial for the patient's well-being. Dismissing the patient's concerns (Option A) or ignoring their frustration (Option C) can lead to a breakdown in communication and trust, which may ultimately impact the patient's compliance with the treatment plan. Similarly, telling the patient that they have no choice but to follow the treatment plan (Option D) can be perceived as dismissive and confrontational, which is not conducive to promoting patient-centered care.

Correct Answer: A

Rationale: The patient requiring a dressing change of post-caesarian surgery should be assigned to the midwife because this task involves specialized knowledge and skills related to wound care and post-operative care. Performing a dressing change for a post-caesarian surgery patient requires expertise to ensure proper hygiene, wound healing, and prevention of post-operative complications. This task goes beyond the scope of practice for a nursing assistant and should be done by a healthcare professional with higher qualifications and training, such as a midwife.

Correct Answer: D

Rationale: The best time for an incontinent patient to take diuretics is at bedtime. This timing allows for increased urine production during the night, consequently reducing the need for frequent toileting during the day. By taking the diuretic at bedtime, the patient can manage their incontinence more effectively and have better rest without disruptions from frequent urination during the day.

Correct Answer: A

Rationale: IgA is the primary immunoglobulin class involved in providing passive immunity to newborn infants through breast milk. IgA antibodies are highly concentrated in colostrum and breast milk, offering important protection to newborns against infections. IgG antibodies can also be passed from the mother to the fetus through the placenta, providing passive immunity during pregnancy, but IgA is the main immunoglobulin class transferred through breast milk for protecting the infant's gastrointestinal and respiratory tracts. IgE is mainly involved in allergies and hypersensitivity reactions, while IgM is an early responder in the immune response to infections.

Correct Answer: C

Rationale: The described clinical presentation of a yellowish-white spot on the cornea with a ring of inflammation, along with branching, filamentous opacities extending from the corneal lesion, is highly suggestive of fungal keratitis. Fungal keratitis is commonly caused by filamentous fungi such as Fusarium and Aspergillus species. The characteristic finding of branching, filamentous opacities seen on slit-lamp examination is classic for fungal infections of the cornea. It is important to promptly diagnose and treat fungal keratitis since delayed or inadequate management can result in vision-threatening complications.
