1. A client is receiving heparin therapy. Which of the following laboratory tests should be monitored to evaluate the effectiveness of the therapy?

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the most appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works on the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps assess its anticoagulant effect. Therapeutic levels of aPTT for clients on heparin therapy are typically 1.5 to 2.5 times the control value. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, which acts on the extrinsic pathway of the coagulation cascade. Complete blood count (CBC) is not specific for monitoring the effectiveness of heparin therapy.

2. The nurse is preparing to administer an intravenous dose of furosemide (Lasix) to a client with heart failure. The nurse should monitor for which potential side effect?

Correct answer: C

Rationale: Furosemide is a loop diuretic that works by promoting the excretion of water and electrolytes, including potassium. This loss of potassium can lead to hypokalemia, which can be a potential side effect of furosemide administration. Hypokalemia can result in cardiac dysrhythmias and other complications, especially in clients with heart failure who may already have compromised cardiac function. Therefore, monitoring for signs of hypokalemia, such as muscle weakness, cardiac irregularities, and fatigue, is essential when administering furosemide. Choice A, hypertension, is incorrect because furosemide is actually used to treat hypertension by reducing excess fluid in the body. Choice B, hyperkalemia, is incorrect as furosemide causes potassium loss, leading to hypokalemia. Choice D, hypoglycemia, is unrelated to the mechanism of action of furosemide and is not a common side effect associated with its administration.

3. A client is admitted with an arterial ischemic leg ulcer. The nurse expects to note that this ulcer has which typical characteristic?

Correct answer: B

Rationale: Arterial ischemic ulcers are typically characterized by being deep and painful, often with a pale or necrotic base. The lack of adequate blood flow leads to tissue damage, resulting in these ulcers having a deep appearance and causing significant pain to the individual. The other options are not commonly associated with arterial ischemic ulcers; a dark pink base, very slight pain, or brown pigmentation of surrounding skin are not typical features of this type of ulcer.

4. A client with chronic obstructive pulmonary disease (COPD) is prescribed a metered-dose inhaler (MDI) with a spacer. Which instruction should the nurse reinforce to ensure correct use?

Correct answer: A

Rationale: Inhaling deeply and slowly after activating the MDI is the correct instruction to ensure effective delivery of the medication to the lungs. This technique helps the medication reach the lower airways where it can be most beneficial in managing COPD symptoms. Inhaling too quickly or not deeply enough may result in improper drug delivery and reduce the effectiveness of the treatment. Holding the breath for 5 seconds after inhaling the medication (Choice B) may not be necessary and could cause discomfort without additional benefits. Rinsing the mouth immediately after using the MDI (Choice C) is not necessary unless specified by the healthcare provider. Exhaling fully before placing the mouthpiece in the mouth (Choice D) is not ideal as it may result in inadequate medication delivery to the lungs.

5. The healthcare professional is assessing a client who presents with jaundice. Which assessment finding is most important for the healthcare professional to follow up on?

Correct answer: D

Rationale: Elevated serum amylase and lipase levels are indicative of pancreatitis, a serious condition that can manifest with jaundice. Timely follow-up is crucial to manage pancreatitis and its complications effectively in a jaundiced client. Choices A, B, and C are less critical in this scenario. Urine specific gravity within normal range, frothy tea-colored urine, and clay-colored stools can be associated with various conditions but are not directly indicative of pancreatitis, which is the most concerning condition associated with jaundice.
