Correct Answer: C

Rationale: The correct answer is C: Diagnostic reasoning. Diagnostic reasoning involves using assessment data and critical thinking skills to develop a nursing diagnosis. This process includes analyzing and interpreting data to make clinical judgments about the patient's health status. A: Assigning clinical cues is incorrect because this refers to identifying and documenting specific observations or findings during the assessment process, not the process of developing a nursing diagnosis. B: Defining characteristics is incorrect because this refers to the specific symptoms or manifestations used to support a nursing diagnosis, not the overall process of diagnostic reasoning. D: Diagnostic labeling is incorrect because this refers to assigning a formal name to the nursing diagnosis, not the process of critically analyzing assessment data to develop it.

Correct Answer: B

Rationale: The correct answer is B: To prevent cerebrospinal fluid (CSF) leakage. 1. Positioning is crucial to prevent CSF leakage as the spinal block is administered into the sub-arachnoid space where CSF is present. 2. Incorrect Answers: A: Positioning is not related to preventing confusion in this context. C: Seizures are not typically associated with spinal block anesthesia. D: Cardiac arrhythmias are not directly impacted by the client's positioning for a spinal block.

Correct Answer: B

Rationale: The correct answer is B: Lung cancer. Lung cancer causes the most deaths in women due to its high mortality rate. It is often diagnosed at an advanced stage, leading to poorer outcomes. Breast cancer, although common, has a lower mortality rate compared to lung cancer. Brain cancer is relatively rare in comparison. Colon and rectal cancer, while significant, do not surpass lung cancer in terms of causing the most deaths in women.

Correct Answer: A

Rationale: The correct answer is A because tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation. Sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate and dilated pupils to prepare the body for quick action. Choice B is incorrect because hypoglycemia and headache are not specific to sympathetic nervous system function. Choice C is incorrect because increased peristalsis and abdominal cramping are more indicative of parasympathetic nervous system activity. Choice D is incorrect because pupil constriction and bronchoconstriction are actions of the parasympathetic nervous system, responsible for rest and digest functions.

Correct Answer: A

Rationale: The presence of redness, swelling, and induration at the wound site are indicative of infection. Redness and swelling suggest inflammation, while induration indicates tissue hardening and can be a sign of infection spreading. Infection can delay healing and lead to complications if not treated promptly. Evisceration refers to wound opening with protrusion of internal organs, not indicated by the symptoms. Dehiscence is the partial or complete separation of wound layers, not represented by the symptoms. Hemorrhage involves excessive bleeding, which is not described in the scenario. Therefore, choice A is correct as it aligns with the signs observed and is the most appropriate response for the situation.
