The nurse interprets this as?

Correct Answer: C

Rationale: The nurse interprets this as respiratory alkalosis because the patient is likely experiencing hyperventilation, leading to a decrease in CO2 levels and respiratory alkalosis. This is indicated by an increase in pH and a decrease in PaCO2 on arterial blood gas analysis. Metabolic acidosis (choice B) is characterized by low pH and low bicarbonate levels, not seen in this scenario. Respiratory acidosis (choice A) is characterized by high PaCO2 levels and low pH, which is not the case here. Metabolic alkalosis (choice D) is characterized by high pH and high bicarbonate levels, which is not consistent with the patient's presentation.

Correct Answer: B

Rationale: The correct answer is B (Lifetime dependency on hormone replacement) because after hypophysectomy (removal of the pituitary gland), patients will no longer produce essential hormones like growth hormone, thyroid-stimulating hormone, etc. Therefore, they will require lifelong hormone replacement therapy to maintain normal bodily functions. A: Abnormal distribution of body hair is not directly related to hypophysectomy. C: While fluid intake may be important post-surgery, it is not the primary focus of teaching. D: There is typically no need for repeat surgical procedures after a hypophysectomy, as it is a one-time surgery to address specific issues. In summary, choice B is correct as it directly addresses the long-term implications of the surgery on hormone production and the need for replacement therapy, while the other choices are not directly relevant to the post-operative care of hypophysectomy patients.

Correct Answer: A

Rationale: The correct answer is A: Use aseptic technique for the insertion site. Aseptic technique is necessary to prevent infection when accessing the intracranial pressure monitoring system. Aseptic technique involves maintaining a sterile field during the insertion process, reducing the risk of introducing pathogens. Using clean technique for cleansing connections (choice B) may introduce contaminants to the insertion site. Sterile technique for cleansing the insertion site (choice C) is not necessary and may be overly stringent. Closing leaks in the tubing with tape (choice D) does not address the prevention of infection at the insertion site.

Correct Answer: C

Rationale: Step-by-step rationale: 1. The cranial nerve responsible for facial expression is CN VII, the facial nerve. 2. When a neurologist asks a patient to smile, they are testing the function of CN VII. 3. CN II (optic nerve) is responsible for vision, not facial expression. 4. CN X (vagus nerve) is responsible for various functions like heart rate and digestion, not facial expression. 5. CN XI (accessory nerve) is responsible for shoulder movement, not facial expression. Summary: Testing a patient's ability to smile involves assessing the function of CN VII, the facial nerve. Choices A, B, and D are incorrect as they are associated with different functions and not responsible for controlling facial muscles.

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.
