Nokea
Which of the following is a rare genetic disorder that affects the lungs, liver, and skin, causing the buildup of a specific protein that damages organs?
- A. Alpha-1 antitrypsin deficiency
- B. Cystic fibrosis
- C. Wegener's granulomatosis
- D. Marfan syndrome
Correct Answer: A
Rationale: Alpha-1 antitrypsin deficiency is the correct answer. This disorder affects the lungs, liver, and skin due to the buildup of a specific protein (alpha-1 antitrypsin) that damages organs. This deficiency can lead to lung and liver diseases. Cystic fibrosis primarily affects the lungs and digestive system, not the liver and skin. Wegener's granulomatosis is a condition that affects the blood vessels, lungs, and kidneys, not the liver. Marfan syndrome is a connective tissue disorder that affects the heart, blood vessels, bones, and eyes, not the lungs, liver, and skin.

What is a condition where the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients?
- A. Stroke
- B. Heart attack
- C. Pulmonary embolism
- D. Pneumonia
Correct Answer: A
Rationale: The correct answer is A: Stroke. A stroke occurs when the blood supply to part of the brain is interrupted or reduced, leading to brain tissue not receiving enough oxygen and nutrients. This can result in permanent brain damage or even death.
Choice B: Heart attack, involves a blockage in the blood vessels supplying the heart muscle, not the brain.
Choice C: Pulmonary embolism, is a blockage in the arteries of the lungs, not the brain.
Choice D: Pneumonia, is an infection in the lungs and does not directly involve the brain's blood supply.
In summary, a stroke specifically affects the brain's blood supply and can lead to serious consequences, unlike the other conditions mentioned.
What is a chronic condition where the blood pressure in the arteries is persistently elevated, increasing the risk of heart disease and stroke?
- A. Hypertension
- B. Hypotension
- C. Hyperlipidemia
- D. Hyperglycemia
Correct Answer: A
Rationale: The correct answer is A: Hypertension. Hypertension is characterized by persistently elevated blood pressure, which increases the risk of heart disease and stroke. This condition is commonly referred to as high blood pressure. Hypotension (B) is the opposite, indicating low blood pressure. Hyperlipidemia (C) is high levels of fats in the blood, not directly related to blood pressure. Hyperglycemia (D) is high blood sugar levels, also not directly related to blood pressure. Therefore, based on the definition and associated health risks, A is the correct choice.
The healthcare provider is monitoring a client on an ACE inhibitor. What lab value is most important to monitor?
- A. Potassium
- B. Sodium
- C. Creatinine
- D. Calcium
Correct Answer: A
Rationale: The correct answer is A: Potassium. ACE inhibitors can cause hyperkalemia, so monitoring potassium levels is crucial to prevent potential life-threatening complications. High potassium levels can lead to cardiac arrhythmias. Sodium levels are not typically affected by ACE inhibitors. Creatinine is important to monitor for kidney function but not specific to ACE inhibitors. Calcium levels are not directly affected by ACE inhibitors.
A client with dysrhythmia has decreased cardiac output. Which of the following nursing interventions is essential to maintain adequate cardiac output?
- A. Encourage mild exercises
- B. Place the client in supine position
- C. Ensure a client IV access
- D. Provide supplemental oxygen
Correct Answer: D
Rationale: Supplemental oxygen improves oxygen delivery to tissues, supporting cardiac output in clients with dysrhythmias.
This is a type of therapy that involves removing fluid from the lungs, typically through the use of diuretics.
- A. Diuretic therapy
- B. Oxygen therapy
- C. Inhaler therapy
- D. Antihistamine therapy
Correct Answer: A
Rationale: The correct answer is A: Diuretic therapy. This is because diuretics are medications used to remove excess fluid from the body, including the lungs. By increasing urine output, diuretics help reduce fluid buildup in the lungs, making it easier to breathe. Oxygen therapy (B) delivers oxygen to the lungs but does not involve removing fluid. Inhaler therapy (C) is used for respiratory conditions like asthma but does not remove fluid from the lungs. Antihistamine therapy (D) is used to treat allergies and does not address fluid buildup in the lungs. Thus, diuretic therapy is the most appropriate choice for removing fluid from the lungs.
