1. The healthcare provider is preparing to administer heparin to a client. What lab value should be monitored?

• A. PT/INR
• B. aPTT
• C. Platelet count
• D. Hemoglobin

Correct answer: B

Rationale: The correct lab value that should be monitored when administering heparin is the aPTT (activated partial thromboplastin time). Heparin affects the intrinsic pathway of the coagulation cascade, and aPTT is a sensitive measure to assess the effectiveness of heparin therapy. Monitoring aPTT helps in adjusting the heparin dose to maintain the desired anticoagulant effect. PT/INR is more specific to monitor warfarin therapy, not heparin. Platelet count and hemoglobin levels are important parameters to assess bleeding tendencies and oxygen-carrying capacity but are not directly related to monitoring heparin therapy.

2. The client on atorvastatin (Lipitor) should be advised to report which of the following symptoms?

• A. Muscle pain
• B. Headache
• C. Nausea
• D. Dizziness

Correct answer: A

Rationale: The correct answer is A: Muscle pain. Muscle pain can be a sign of rhabdomyolysis, a serious side effect of statins like atorvastatin. Rhabdomyolysis is a condition where muscle fibers break down rapidly and release their contents into the bloodstream, which can lead to kidney damage. Headache, nausea, and dizziness are not commonly associated with atorvastatin use and are less likely to indicate a serious adverse reaction compared to muscle pain.

3. What is a condition where the heart's electrical impulses are delayed or blocked, leading to a slower or irregular heartbeat?

• A. Heart block
• B. Tachycardia
• C. Bradycardia
• D. Arrhythmia

Correct answer: A

Rationale: Heart block is the correct answer because it specifically refers to a condition where the heart's electrical impulses are delayed or blocked, resulting in a slower or irregular heartbeat. Tachycardia (choice B) is a condition characterized by a fast heart rate, Bradycardia (choice C) is a slow heart rate, and Arrhythmia (choice D) is a general term used to describe any abnormal heart rhythm, which may or may not involve delays or blocks in electrical impulses.

4. What is a condition where the lung's air sacs (alveoli) are damaged and enlarged, leading to breathlessness?

• A. Emphysema
• B. Chronic bronchitis
• C. Asthma
• D. Pulmonary fibrosis

Correct answer: A

Rationale: Emphysema is the correct answer. It is a condition where the air sacs in the lungs are damaged and enlarged, leading to breathlessness. Chronic bronchitis is characterized by inflammation of the bronchial tubes, not the alveoli. Asthma involves airway inflammation and constriction, not alveolar damage. Pulmonary fibrosis is a condition where lung tissue becomes thickened and scarred, different from the alveolar damage seen in emphysema.

5. Which condition involves the body's immune system attacking the lungs and kidneys, causing severe respiratory and renal damage?

• A. Goodpasture syndrome
• B. Sarcoidosis
• C. Wegener's granulomatosis
• D. Interstitial lung disease

Correct answer: A

Rationale: Goodpasture syndrome is the correct answer. It is an autoimmune disease characterized by the immune system attacking the lungs and kidneys, leading to bleeding in the lungs and kidney failure. Sarcoidosis primarily affects the lungs and lymph nodes, not the kidneys. Wegener's granulomatosis affects the lungs, sinuses, and kidneys, but it is characterized by inflammation of blood vessels. Interstitial lung disease involves scarring of the lung tissue, not direct immune system attacks on the lungs and kidneys.
