The client is being assessed for possible pernicious anemia. Which finding would support this diagnosis?

Correct Answer: C

Rationale: The correct answer is a red, beefy tongue, which is characteristic of pernicious anemia due to the atrophy of the papillae on the tongue. This finding is known as glossitis. A red, beefy tongue is a classic sign of pernicious anemia. Choice A, weight loss of 10 pounds in 2 weeks, is non-specific and not a typical finding in pernicious anemia. Choice B, complaints of numbness and tingling in the extremities, are more indicative of peripheral neuropathy, a common symptom of vitamin B12 deficiency, which can be seen in pernicious anemia. Choice D, a hemoglobin level of 12.0 g/dL, falls within the normal range and does not specifically point towards pernicious anemia, which is characterized by low hemoglobin levels due to impaired absorption of vitamin B12.

Correct Answer: C

Rationale: The correct answer is Buck's traction. This intervention is used to realign the fractured femur, reduce spasms, and alleviate pain. Placing the client in the Trendelenburg position is inappropriate for a femur fracture, making answer A incorrect. While ice may be used post-repair, applying it to the entire extremity is unnecessary, so answer B is wrong. An abduction pillow is typically employed following a total hip replacement, not for a fractured femur, rendering answer D incorrect.

Correct Answer: B

Rationale: Lidocaine is used to treat ventricular tachycardia. This medication slowly exerts an antiarrhythmic effect by increasing the electrical stimulation threshold of the ventricles without depressing the force of ventricular contractions. It is not used for atrial arrhythmias; thus, answer A is incorrect. Answers C and D are incorrect because lidocaine does not slow the heart rate, so it is not used for heart block or bradycardia.

Correct Answer: B

Rationale: The correct answer is to ask the client to void immediately before the study. For an intravenous pyelogram, the client may have orders for laxatives or enemas, so ensuring the client voids before the test is important to prevent obscuring visualization of the kidney, ureters, and bladder. Choice A is incorrect because there is no need to force fluids before the procedure. Choice C is incorrect as medications affecting the central nervous system should not be held unless specified by the healthcare provider. Choice D is incorrect as covering the reproductive organs with an x-ray shield is not necessary for an intravenous pyelogram.

Correct Answer: D

Rationale: Quinidine can cause widened Q-T intervals and heart block, leading to a prolonged QT interval on the ECG. Other signs of myocardial toxicity associated with quinidine include notched P waves and widened QRS complexes. Common side effects of quinidine include diarrhea, nausea, and vomiting, while less common effects may include tinnitus, vertigo, headache, visual disturbances, and confusion. Monitoring for a prolonged QT interval is crucial due to the potential risk of serious arrhythmias. Choices A, B, and C are not typically associated with the use of quinidine and are therefore incorrect in this context.
