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 purpose of asking Nurse Rosie to submit an Incident Report (IR) is most likely to note patterns of incidences in the same unit. Incident reports are essential tools in healthcare settings to track and analyze unexpected events, errors, or situations that may impact patient care and safety. By collecting and reviewing incident reports, the head nurse can identify trends, patterns, or commonalities in the occurrences within the unit. This information allows for targeted interventions, improvements in practices, and enhanced patient safety. Therefore, asking Nurse Rosie to submit an IR would serve the purpose of noting patterns of incidences in the same unit for proactive and quality care delivery.

Correct Answer: B

Rationale: Proton pump inhibitors (PPIs) are commonly prescribed for conditions involving excessive stomach acid production, such as peptic ulcer disease. One of the potential adverse effects of PPIs, such as omeprazole or pantoprazole, is the risk of hypokalemia. Hypokalemia is a condition characterized by low levels of potassium in the bloodstream. Prolonged use of PPIs can inhibit the absorption of potassium in the intestines, leading to a decrease in potassium levels in the body. Hypokalemia can present with symptoms such as muscle weakness, fatigue, irregular heartbeat, and in severe cases, it can result in life-threatening complications like cardiac arrhythmias. Therefore, it is essential for the nurse to closely monitor the patient for signs and symptoms of hypokalemia while on PPI therapy, especially if the patient is at risk for developing electrolyte imbalances.

Correct Answer: B

Rationale: Meconium-stained amniotic fluid indicates that the fetus may have passed stool in utero, which can lead to potential respiratory problems once born due to meconium aspiration. The priority action for the nurse in this situation is to prepare for immediate delivery to expedite the removal of the fetus from the contaminated environment and provide necessary interventions such as suctioning of the airway to prevent aspiration of meconium. Prompt delivery is crucial to minimize the risk of complications related to meconium aspiration syndrome. Administering oxygen, inserting a urinary catheter, and notifying the neonatal resuscitation team can be important subsequent actions, but the immediate focus should be on delivering the baby.

Correct Answer: B

Rationale: Warming up ofloxacin eardrops before administering is done to prevent dizziness, which can occur if a cold solution is placed in the ear. Holding the bottle with hands for about 1 to 2 minutes is usually sufficient to warm up the solution to a comfortable temperature for the patient. Warming the solution for too long, such as 5-6 minutes, may not be necessary and could potentially waste time. So, the correct duration for warming up ofloxacin eardrops is 1 to 2 minutes.
