Correct Answer: D

Rationale: Correct Answer: D - Lubricating eye drops Rationale: Lubricating eye drops help prevent complications such as corneal abrasions in patients with Bell's Palsy by keeping the eye moist and preventing dryness. Bell's Palsy can cause difficulty in closing the eye properly, leading to dryness and potential damage to the cornea. Using lubricating eye drops helps maintain eye health. Summary of Incorrect Choices: A: Megavitamin therapy - Not directly related to preventing complications in Bell's Palsy. B: Application of ice to the affected area - Ice may not address eye dryness or prevent corneal abrasions. C: Elastic bandages - Not relevant to preventing complications associated with Bell's Palsy.

Correct Answer: C

Rationale: Objective data are measurable and observable facts obtained through physical examination or diagnostic tests. In this case, "Respirations 16" is a quantifiable and observable measurement, making it objective data. It is not influenced by personal interpretation or feelings. The other choices, such as "States 'doesn't feel good'", "Reports a headache", and "Nauseated" are subjective data because they are based on the patient's feelings or experiences, which can vary depending on individual perception and interpretation, making them less reliable for making clinical decisions. By focusing on objective data like "Respirations 16", the nurse can provide a more accurate assessment of the patient's condition.

Correct Answer: C

Rationale: The correct answer is C (280 to 295mOsm/kg) because serum osmolality is primarily determined by sodium, glucose, and blood urea nitrogen levels. Normal serum sodium range is 135-145 mEq/L, which corresponds to an osmolality range of 280-295 mOsm/kg. Choices A and B are incorrect as they do not align with normal serum sodium levels. Choice D is incorrect as it includes an excessively wide range that is not consistent with normal osmolality values.

Correct Answer: B

Rationale: The correct answer is B because having the head of the bed at a 30-degree angle can cause the radioactive material to shift, potentially leading to an uneven distribution of radiation. This could result in harmful exposure to surrounding tissues. A: Maintaining the client on strict bed rest is important to prevent displacement of the radioactive applicator. C: Providing a complete bed bath each morning is necessary for hygiene and does not pose a radiation hazard. D: Checking the applicator's position every 4 hours is essential to ensure proper placement and does not indicate a radiation hazard.

Correct Answer: C

Rationale: The correct answer is C: 125 mL/h. To calculate the infusion rate per hour, we divide the total volume (1000 mL) by the total time in hours (8 hours). 1000 mL / 8 hours = 125 mL/h. This ensures a consistent and accurate infusion rate throughout the 8-hour period. Choice A (80 mL/h) is incorrect because it underestimates the infusion rate. Choice B (100 mL/h) is incorrect because it does not divide the total volume by the total time correctly. Choice D (150 mL/h) is incorrect because it overestimates the infusion rate.
