1. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?

• A. Parathyroid hormone
• B. Insulin
• C. Cortisol
• D. Thyroxine

Correct answer: A

Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.

2. After adding feeding solution to a client's tube feeding system as seen in the picture, what action should the PN take next?

• A. Remove the air from the solution bag
• B. Obtain a piston syringe and irrigation set
• C. Record the solution added as fluid intake
• D. Calculate the rate of flow of the solution

Correct answer: B

Rationale: After adding feeding solution, obtaining a piston syringe and irrigation set is necessary to flush the feeding tube and ensure patency before starting the feeding. This helps prevent blockages and ensures proper delivery of the nutritional solution. Option A is incorrect because removing air from the solution bag is not the immediate next step after adding the feeding solution. Option C is incorrect as recording the solution added as fluid intake is important but not the immediate next step. Option D is incorrect as calculating the rate of flow of the solution is not the next step after adding the feeding solution.

3. Which intervention is most appropriate when caring for a patient experiencing a tonic-clonic seizure?

• A. Restrain the patient to prevent injury
• B. Place a tongue depressor in the patient's mouth
• C. Turn the patient to the side to maintain an open airway
• D. Attempt to stop the seizure by holding the patient’s arms

Correct answer: C

Rationale: During a tonic-clonic seizure, the priority is to ensure patient safety by maintaining an open airway to prevent aspiration. Turning the patient to the side helps achieve this goal by allowing any fluids to drain out of the mouth, reducing the risk of choking or aspiration. Restraint can lead to injury, placing a tongue depressor can cause harm or obstruct the airway further, and attempting to stop the seizure by holding the patient's arms is ineffective and can also result in injury. Therefore, the most appropriate intervention is to turn the patient to the side.

4. Which cranial nerve is responsible for the sense of smell?

• A. Olfactory nerve
• B. Optic nerve
• C. Trigeminal nerve
• D. Vagus nerve

Correct answer: A

Rationale: The olfactory nerve (Cranial Nerve I) is indeed responsible for the sense of smell. It is located in the nasal cavity and transmits olfactory information to the brain. The optic nerve (Choice B) is responsible for vision, the trigeminal nerve (Choice C) is responsible for sensation in the face, and the vagus nerve (Choice D) is responsible for various functions such as heart rate, digestion, and speech. Therefore, the correct answer is the olfactory nerve (Choice A).

5. When administering parenteral iron, which action would be inconsistent with proper administration?

• A. Using the Z-track method
• B. Using an air bubble to avoid withdrawing medication into subcutaneous tissue
• C. Not massaging the injection site
• D. Using the deltoid muscle for administration

Correct answer: D

Rationale: The correct answer is D: Using the deltoid muscle for administration. Administering parenteral iron in the deltoid muscle is not recommended due to the risk of irritation and pain. The Z-track method (choice A) is preferred to prevent staining and irritation of the skin when administering irritating medications like iron. Using an air bubble (choice B) to avoid withdrawing medication into subcutaneous tissue is a common practice to ensure accurate administration. Not massaging the injection site (choice C) is also a standard practice to prevent potential irritation or bleeding at the injection site.
