Correct Answer: C

Rationale: The correct action the nurse should take is to wrap monitoring cords with stockinette. This measure ensures that the latex in the cords does not come into contact with the client's skin, reducing the risk of an allergic reaction. Applying tape to the client's skin before surgery (Choice A) may expose the client to latex if the tape contains latex. Ensuring the surgical suite is well-ventilated (Choice B) is important for overall safety but does not specifically address the client's latex allergy. Scheduling the surgery at the end of the day (Choice D) is not directly related to preventing latex exposure and allergic reactions.

Correct Answer: C

Rationale: The correct answer is C. There should be 2 cm of water in the water seal chamber of the chest tube system. A level of 1 cm may indicate a leak or compromised functionality that requires intervention. Choices A, B, and D are not findings that necessarily require immediate intervention. Tidaling with spontaneous respirations is an expected finding, the drainage collection chamber being 1/3 full is within normal limits, and a suction chamber pressure of -20 cm H2O indicates appropriate suction for chest drainage.

Correct Answer: D

Rationale: The correct answer is D: Red, open sores in the mouth. Stomatitis, a common side effect of chemotherapy, presents with red, open sores in the mouth, which can be painful and increase the risk of infection. Choices A, B, and C are incorrect because stomatitis typically does not manifest as dry, cracked lips, bleeding gums, or foul-smelling breath.

Correct Answer: A

Rationale: The correct answer is A: Butterfly rash on the face. A butterfly-shaped rash across the nose and cheeks is a classic symptom of systemic lupus erythematosus (SLE), an autoimmune disease. Weight gain (Choice B) is not typically associated with SLE. Joint deformities (Choice C) are more commonly seen in conditions like rheumatoid arthritis. Increased hair growth (Choice D) is not a typical finding in SLE.

Correct Answer: A

Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.
