1. A client has a long history of hypertension. Which category of medication would the nurse expect to be ordered to avoid chronic kidney disease (CKD)?
- A. Antibiotic
- B. Histamine blocker
- C. Bronchodilator
- D. Angiotensin-converting enzyme (ACE) inhibitor
Correct answer: D
Rationale: The correct answer is D, Angiotensin-converting enzyme (ACE) inhibitor. ACE inhibitors inhibit the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By blocking this conversion, ACE inhibitors promote vasodilation and improve perfusion to the kidneys. Additionally, ACE inhibitors block the breakdown of bradykinin and prostaglandin, further contributing to vasodilation. They also lead to increased renin and decreased aldosterone levels. These effects help in reducing blood pressure and protecting the kidneys in clients with hypertension. Antibiotics are used to fight infections, histamine blockers reduce inflammation, and bronchodilators widen the bronchi, none of which address the underlying processes involved in slowing the progression of chronic kidney disease (CKD) in hypertensive clients.
2. Which of the following is a common cause of chronic obstructive pulmonary disease (COPD)?
- A. Smoking
- B. Asthma
- C. Allergies
- D. Chronic bronchitis
Correct answer: A
Rationale: Smoking is the correct answer as it is a well-established common cause of chronic obstructive pulmonary disease (COPD). Smoking leads to long-term damage to the lungs, contributing to the development of COPD. Choice B, asthma, is not a cause but a separate respiratory condition characterized by airway inflammation and hyperresponsiveness. Allergies, choice C, are not a direct cause of COPD but can exacerbate symptoms in individuals with existing COPD. Chronic bronchitis, choice D, is a type of COPD, not a cause of COPD itself, making it an incorrect choice in this context.
3. A client with renal insufficiency and a low red blood cell count asks, 'Is my anemia related to the renal insufficiency?' How should the nurse respond?
- A. Red blood cells produce erythropoietin, which increases blood flow to the kidneys.
- B. Your anemia and renal insufficiency are related to inadequate vitamin D and a loss of bone density.
- C. Erythropoietin is usually released from the kidneys and stimulates red blood cell production in the bone marrow.
- D. Kidney insufficiency inhibits active transportation of red blood cells throughout the blood.
Correct answer: C
Rationale: The correct answer is C. Erythropoietin is produced in the kidney and is released in response to decreased oxygen tension in the renal blood supply. Erythropoietin stimulates red blood cell production in the bone marrow. Anemia in renal insufficiency is often due to decreased erythropoietin production. Anemia and renal insufficiency are not manifestations of vitamin D deficiency as stated in choice B. Choice A is incorrect as erythropoietin does not increase blood flow to the kidneys. Choice D is incorrect because kidney insufficiency does not inhibit active transportation of red blood cells throughout the blood; rather, it affects erythropoietin production and subsequent red blood cell formation.
4. A female client taking oral contraceptives reports to the nurse that she is experiencing calf pain. What action should the nurse implement?
- A. Determine if the client has also experienced breast tenderness and weight gain.
- B. Encourage the client to begin a regular, daily program of walking and exercise.
- C. Advise the client to notify the healthcare provider for immediate medical attention.
- D. Tell the client to stop taking the medication for a week to see if symptoms subside.
Correct answer: C
Rationale: Calf pain is indicative of thrombophlebitis, a serious, life-threatening complication associated with the use of oral contraceptives which requires further assessment and possibly immediate medical intervention.
5. Which of the following is a sign of hypocalcemia?
- A. Hyperactive reflexes.
- B. Depressed reflexes.
- C. Muscle cramps.
- D. Seizures.
Correct answer: A
Rationale: Hyperactive reflexes are a classic sign of hypocalcemia. Hypocalcemia leads to increased neuromuscular excitability, resulting in hyperactive reflexes. Depressed reflexes (Choice B) are not typically associated with hypocalcemia. Muscle cramps (Choice C) can be seen in hypocalcemia due to muscle irritability but are not a specific sign. Seizures (Choice D) can occur in severe cases of hypocalcemia but are not as common as hyperactive reflexes.
