ATI Exit Exam

Correct Answer: A

Rationale: A hemoglobin level of 11.2 g/dL is below the normal range for a client who is 36 weeks gestation and should be reported to the provider.

Correct Answer: B

Rationale: The correct answer is B: aPTT. The activated partial thromboplastin time (aPTT) is monitored to assess the therapeutic effect of heparin and to adjust the infusion rate if needed. Monitoring hemoglobin levels (choice A) is important for assessing anemia but is not specific to heparin therapy. INR (choice C) is used to monitor the effects of warfarin, not heparin. Platelet count (choice D) is important to monitor for heparin-induced thrombocytopenia, but aPTT is the primary laboratory value used to monitor heparin therapy.

Correct Answer: B

Rationale: The correct answer is B: 'Contact your provider if you experience visual changes.' Visual changes, such as blurred or yellow vision, can indicate digoxin toxicity and should be reported immediately to the healthcare provider for further evaluation and management. Choice A is incorrect because digoxin can be taken with antacids. Choice C is incorrect because increasing potassium intake can lead to hyperkalemia when taking digoxin. Choice D is incorrect because increased urination is not a common side effect of digoxin.

Correct Answer: C

Rationale: The correct answer is C: Activated partial thromboplastin time (aPTT). aPTT is specifically used to monitor and regulate heparin therapy as it assesses the intrinsic pathway of coagulation, which heparin affects. Options A and B, Prothrombin time (PT) and International Normalized Ratio (INR), are used to monitor warfarin therapy, not heparin. Option D, Fibrinogen levels, is not the primary test used to monitor heparin therapy.

Correct Answer: C

Rationale: The correct action the nurse should take when preparing to administer heparin subcutaneously is to administer the medication within 5 cm (2 in) of the umbilicus. This practice ensures proper subcutaneous delivery of the medication. Choice A is incorrect because a smaller gauge needle, typically 25-26 gauge, is used for subcutaneous injections. Choice B is incorrect as heparin should not be injected into the deltoid muscle but rather into fatty tissue. Choice D is incorrect as massaging the injection site after administration can lead to tissue irritation or bruising.
