Foundations and Adult Health Nursing Study Guide Answers Questions
Question 1 of 5
A patient with chronic kidney disease presents with metabolic acidosis. Which compensatory mechanism is the body most likely to employ to normalize pH?
Correct Answer: B
Rationale: In a patient with chronic kidney disease presenting with metabolic acidosis, the compensatory mechanism the body is most likely to employ to normalize pH is increased bicarbonate reabsorption in the kidneys. The kidneys play a crucial role in maintaining acid-base balance by regulating bicarbonate levels in the blood. In metabolic acidosis, there is an excess of non-volatile acids in the body, leading to a decrease in blood pH. To compensate for this acidosis, the kidneys increase the reabsorption of filtered bicarbonate ions from the renal tubules back into the blood. This process helps to raise the bicarbonate levels in the blood, which in turn helps to neutralize excess hydrogen ions and restore the blood pH towards normal levels. Hyperventilation (A) is a compensatory mechanism for respiratory acidosis, not metabolic acidosis. Increased renal excretion of hydrogen ions (C) and decreased renal excretion of bicarbonate ions
Question 2 of 5
A patient with a history of heart failure is prescribed carvedilol. Which parameter should the nurse monitor closely during carvedilol therapy?
Correct Answer: C
Rationale: Carvedilol is a beta-blocker primarily used to manage heart failure and hypertension. Monitoring blood pressure closely during carvedilol therapy is crucial because it helps assess the drug's effectiveness in managing heart failure and controlling hypertension. Carvedilol works by blocking certain receptors in the heart and blood vessels, which can lower blood pressure. Monitoring blood pressure fluctuations allows healthcare providers to adjust the dosage accordingly to achieve optimal results and prevent potential complications in patients with heart failure. While monitoring blood glucose levels, serum potassium levels, and liver function tests are essential in managing other conditions or medications, the priority in a patient being prescribed carvedilol for heart failure is to monitor blood pressure levels.
Question 3 of 5
A patient with a history of chronic obstructive pulmonary disease (COPD) is prescribed a metered-dose inhaler (MDI) with a spacer. Which instruction should the nurse include in the demonstration of MDI use?
Correct Answer: A
Rationale: The correct instruction for using a metered-dose inhaler (MDI) with a spacer for a patient with COPD is to inhale slowly and deeply while pressing the canister. This technique helps ensure that the medication reaches the lungs effectively. Inhaling slowly and deeply allows the medication to be properly delivered to the airways, maximizing its effectiveness in treating the symptoms of COPD. This instruction helps the patient coordinate pressing the canister with their inhalation, which is crucial for proper medication delivery in COPD management.
Question 4 of 5
A patient with a history of chronic obstructive pulmonary disease (COPD) is prescribed tiotropium (Spiriva) inhaler. Which instruction should the nurse include in patient education about tiotropium inhaler use?
Correct Answer: B
Rationale: Tiotropium (Spiriva) is an anticholinergic bronchodilator used for the management of COPD. A common side effect of anticholinergic medications is dry mouth. Rinsing the mouth with water after using the inhaler can help reduce the risk of developing oral thrush or other mouth infections due to dryness. This instruction helps promote good oral hygiene and decreases the potential side effects associated with tiotropium inhaler use. This teaching is important for patients to follow to ensure their overall health and well-being while using the medication.
Question 5 of 5
A patient is prescribed an angiotensin-converting enzyme (ACE) inhibitor for heart failure. Which laboratory parameter should the nurse monitor closely during ACE inhibitor therapy?
Correct Answer: A
Rationale: The nurse should monitor serum potassium levels closely during ACE inhibitor therapy because ACE inhibitors can lead to an increase in serum potassium levels, known as hyperkalemia. ACE inhibitors block the conversion of angiotensin I to angiotensin II, which in turn decreases aldosterone secretion. Aldosterone normally acts in the kidneys to reabsorb sodium and water and excrete potassium. Therefore, when aldosterone secretion is decreased due to ACE inhibitor therapy, there can be an increase in potassium retention, potentially leading to hyperkalemia. Monitoring serum potassium levels is essential to prevent complications associated with hyperkalemia, such as cardiac arrhythmias.
