Before Jacob undergoes arthroscopy, the nurse reviews the assessment findings for contraindications for this procedure. Which finding is a contraindication?

Correct Answer: C

Rationale: The correct answer is C because joint flexion of less than 50% indicates limited range of motion, which can affect the success and safety of arthroscopy. Limited flexion may hinder the surgeon's ability to maneuver instruments inside the joint. Joint pain (choice A) is a common reason for arthroscopy, not a contraindication. Joint deformity (choice B) may also be a reason for arthroscopy, not a contraindication. Joint stiffness (choice D) can be addressed during arthroscopy, so it is not a contraindication.

Correct Answer: B

Rationale: The correct answer is B because dyspnea, tachycardia, and pallor are classic signs of iron-deficiency anemia. - Dyspnea is due to decreased oxygen-carrying capacity from low hemoglobin levels. - Tachycardia occurs as the heart compensates for the decreased oxygen by pumping faster. - Pallor results from reduced red blood cell production. The other choices are incorrect: - A: Night sweats, weight loss, and diarrhea are not typically associated with iron-deficiency anemia. - C: Nausea, vomiting, and anorexia are more commonly seen in other types of anemia or gastrointestinal issues. - D: Itching, rash, and jaundice are not specific to iron-deficiency anemia.

Correct Answer: C

Rationale: Rationale: 1. A complete blood count (CBC) assesses various components like red blood cells, white blood cells, and platelets. 2. Hematocrit (HCT) measures the percentage of red blood cells in the blood, and hemoglobin (Hb) is a protein in red blood cells that carries oxygen. 3. Low HCT and Hb levels could indicate anemia, which may affect oxygen delivery to tissues and increase surgical risks. 4. Choices A, B, and D are incorrect because CBC does not directly assess hepatic function (A), urine constituents (B), or electrolyte imbalance (D). Summary of Incorrect Choices: A: Not related to CBC, which focuses on blood cell parameters. B: CBC does not analyze urine constituents but rather blood components. D: Electrolyte imbalance is not typically assessed through a CBC test.

Correct Answer: A

Rationale: The correct answer is A: Ask the woman's family to provide personal items such as photos or mementos. This is the most appropriate action because it can help provide familiar and comforting stimuli for the confused elderly client, potentially reducing her confusion and anxiety. Personal items can also serve as memory aids. Choice B is incorrect because the placement of the bed does not address the client's confusion and unsteady gait. Choice C is incorrect as it does not specifically address the client's confusion and gait issues. Choice D is incorrect because encouraging ambulation without addressing the underlying causes of confusion and unsteadiness may not be safe or effective.

Correct Answer: C

Rationale: The correct answer is C: Avoid foods that in the past caused flatus. This is the most appropriate suggestion because it directly addresses the client's concern about controlling the passage of gas. By avoiding foods that have previously caused gas, the client can potentially reduce the likelihood of experiencing excessive gas with a colostomy. The other options (A, B, D) do not directly address the issue of controlling gas passage and may not be as effective in managing the client's specific concern. It is important to individualize dietary recommendations based on the client's unique needs and experiences to promote optimal comfort and well-being.
