Correct Answer: B

Rationale: The correct answer is B because it addresses the importance of notifying the physician about a painless lump at the top of the chest incision, which could indicate a serious complication like a seroma or hematoma. This is crucial for early detection and intervention. A is incorrect because showers are generally allowed after cardiac surgery as long as the incisions are kept clean and dry. C is incorrect because support hose or elastic stockings are typically recommended to be worn during the day and removed at night to prevent swelling and promote circulation. D is incorrect because resuming sexual relations after cardiac surgery should be based on individual recovery and should be discussed with the healthcare provider, rather than a standard timeframe.

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: The correct answer is C: Generalized seizure. This type of seizure involves both hemispheres of the brain from the onset, leading to loss of consciousness and tonic-clonic jerking. It is characterized by widespread, synchronized electrical discharges. A: Focal seizures start in one area of the brain, leading to localized symptoms without loss of consciousness. B: Jacksonian seizures are a type of focal seizure characterized by a progression of jerking movements from one body part to another. D: Partial seizures involve only one part of the brain, leading to localized symptoms or altered consciousness without loss of awareness.

Correct Answer: C

Rationale: Objective data are measurable and observable, such as vital signs. Respirations of 16 are a specific numerical measurement that can be quantified. This makes choice C the correct answer as it is factual and quantifiable. Choices A, B, and D are subjective data, as they rely on the patient's feelings or experiences, which are open to interpretation and not measurable. Therefore, the nurse should report choice C as objective data as it provides concrete information for assessment and decision-making.
