Correct Answer: B

Rationale: The correct sequence for administering a large volume enema is as follows: 1. Insert the enema tube into the rectum, 2. Administer the enema solution, 3. Clamp the tube, 4. Remove the tube, 5. Wrap the end with tissue. Therefore, the nurse should remove the enema tube from the client's rectum after administering the enema solution. Choices A, C, and D are incorrect because the enema tube should be removed from the rectum after the administration of the solution, not before or during the process.

Correct Answer: B

Rationale: The correct order of steps for this procedure is to first inject air into the NPH insulin bottle to prevent vacuum formation. After injecting air into the NPH insulin, the next step is to withdraw the correct dose of regular insulin from its bottle. This sequence ensures that the regular insulin is drawn after the NPH insulin, preventing contamination and ensuring accurate dosing. Therefore, choice B is correct. Choices A, C, and D are incorrect because air should be injected into the NPH insulin first, not the regular insulin, and the doses should be withdrawn in the appropriate order to maintain the integrity and potency of each insulin type.

Correct Answer: D

Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.

Correct Answer: C

Rationale: The correct answer is C. Offering a variety of foods in small portions is appropriate for a 2-year-old toddler as it helps provide balanced nutrition and allows the child to explore different tastes and textures. Choice A is incorrect because whole milk is recommended up to 2 years old, not until 3 years old. Choice B is incorrect as excessive juice intake can lead to excessive sugar consumption and is not recommended. Choice D is incorrect as popcorn may pose a choking hazard for toddlers and is not a suitable alternative to sweets.

Correct Answer: A

Rationale: Monitoring the white blood cell count is crucial when a patient is undergoing chemotherapy for breast cancer. Chemotherapy can lead to neutropenia, a condition of low white blood cell count, which significantly increases the risk of infections. Monitoring white blood cell count helps healthcare providers intervene promptly to prevent severe infections. Hemoglobin level, while important in assessing oxygen-carrying capacity, is not the priority in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer.
