Nursing Process Questions

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: D

Rationale: The correct answer is D: Sigmoidoscopy. Sigmoidoscopy is a direct visualization procedure that allows for examination of the lower part of the colon and rectum, where colorectal cancer commonly occurs. This procedure can help identify any abnormal growths or polyps that may indicate cancer. Stool hematest (A) detects blood in stool but does not confirm colorectal cancer. Abdominal CT (B) provides imaging of the abdomen but may not definitively diagnose colorectal cancer. CEA scan (C) measures a tumor marker associated with colorectal cancer but is not a definitive diagnostic test. Thus, sigmoidoscopy is the most appropriate diagnostic study for confirming colorectal cancer.

Correct Answer: A

Rationale: The correct answer is A: Prevent clot formation. Heparin is an anticoagulant that inhibits the formation of blood clots. In DIC (Disseminated Intravascular Coagulation), there is excessive clotting throughout the body, leading to organ damage. By administering heparin, we aim to prevent further clot formation and reduce the risk of complications. Choice B is incorrect because heparin does not increase clot formation; it works to inhibit clotting. Choice C is incorrect as heparin does not directly increase blood flow to target organs. Choice D is also incorrect as heparin does not decrease blood flow to target organs; its primary role is anticoagulation.

Correct Answer: A

Rationale: The correct answer is A: Weight. Monitoring daily weight is crucial in assessing fluid retention and worsening heart failure symptoms. Weight gain can indicate fluid overload, a common complication in heart failure. The other choices (B: Appetite, C: Calorie count, and D: Abdominal girth) are not as directly related to monitoring heart failure severity. Appetite and calorie count may be affected by various factors unrelated to heart failure, while abdominal girth may not provide specific information on fluid status. Monitoring weight allows for early intervention and adjustments in treatment to prevent exacerbation of heart failure symptoms.

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.
