PN ATI Capstone Proctored Comprehensive Assessment 2020 A

Correct Answer: A

Rationale: Diltiazem, a calcium channel blocker, can cause hypotension. Administering it to a client who already has hypotension could exacerbate this condition. Therefore, hypotension is a contraindication to the administration of diltiazem. Incorrect Choices: B) Tachycardia is not a contraindication for administering diltiazem in atrial fibrillation as it is commonly used to control the heart rate. C) Decreased level of consciousness may require evaluation but is not a direct contraindication to diltiazem administration. D) History of diuretic use is not a contraindication if the client is not currently experiencing hypotension.

Correct Answer: B

Rationale: The correct answer is B: 'Rifampin can turn body fluids orange.' Rifampin is known to cause orange discoloration of body fluids, including urine. This side effect is harmless and does not indicate a need to stop the medication. Choice A is incorrect because stopping isoniazid will not resolve the orange urine discoloration caused by rifampin. Choice C is unnecessary at this point since the orange urine is a known side effect of rifampin and does not require an urgent provider visit. Choice D is incorrect because bladder irritation is not typically associated with isoniazid.

Correct Answer: A

Rationale: Tamoxifen is an antiestrogen medication used primarily in the treatment and prevention of breast cancer. It works by blocking the effects of estrogen in the breast tissue, thereby acting as an antiestrogenic agent. This makes choice A the correct answer. Choice B, antimicrobial, is incorrect as tamoxifen does not possess antimicrobial properties and is not used to treat infections. Choice C, androgenic, is incorrect as tamoxifen has antiestrogenic effects, not androgenic effects. Choice D, anti-inflammatory, is incorrect as tamoxifen's main therapeutic action is antiestrogenic rather than anti-inflammatory.

Correct Answer: D

Rationale: The correct answer is D, 'All of the Above.' Valproic acid can impact liver function and coagulation. Monitoring the Prothrombin Time (PTT), Aspartate Aminotransferase (AST), and Alanine Aminotransferase (ALT) is crucial. PTT is monitored to assess coagulation status, while AST and ALT are liver enzymes that indicate liver function. Monitoring these values helps detect any potential adverse effects of valproic acid on the liver and blood clotting. Choices A, B, and C are incorrect because each of these laboratory values plays a critical role in evaluating the client's response to valproic acid therapy and detecting associated complications.

Correct Answer: B

Rationale: An aPTT of 90 seconds is elevated, indicating a risk of bleeding due to excessive anticoagulation. The appropriate action is to reduce the infusion rate of heparin to prevent further complications. Administering vitamin K is not indicated for an elevated aPTT due to heparin therapy. Giving the client a low-dose aspirin can further increase the risk of bleeding when combined with heparin. Requesting an INR is not necessary for monitoring heparin therapy; aPTT is the more specific test for assessing heparin's therapeutic effect. Therefore, the correct action for the nurse to prepare to take is to reduce the infusion rate of heparin.
