Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: The cardiovascular disorder most likely responsible for the symptoms described is a pericardial effusion. A pericardial effusion is an accumulation of fluid within the pericardial space surrounding the heart. When a large pericardial effusion is present, it can lead to compression of the heart chambers, resulting in symptoms such as chest pain and dyspnea.

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

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.

Correct Answer: B

Rationale: One of the major differences between Hodgkin's lymphoma and non-Hodgkin's lymphoma is that Hodgkin's lymphoma is considered potentially curable, while non-Hodgkin's lymphoma is typically not curable. Hodgkin's lymphoma is characterized by the presence of Reed-Sternberg cells, which are not found in non-Hodgkin's lymphoma. Additionally, Hodgkin's lymphoma tends to spread in a more orderly and predictable manner through the lymph nodes, making it easier to treat and potentially cure with the appropriate combination of chemotherapy, radiation therapy, and stem cell transplant. On the other hand, non-Hodgkin's lymphoma is a diverse group of lymphomas that can vary greatly in presentation, behavior, and response to treatment, with some subtypes being more aggressive and resistant to treatment. Therefore, the potential for cure is higher in Hodgkin's lymphoma compared to non-Hodgkin's lymph

Correct Answer: C

Rationale: The esophagus is responsible for propelling food from the oral cavity to the stomach through a series of coordinated muscular contractions. These contractions are known as peristalsis. The esophagus is a muscular tube connecting the throat (pharynx) to the stomach and plays a crucial role in moving food bolus from the mouth to the stomach for digestion. The tongue helps in the chewing and swallowing of food, the pharynx is involved in the passage of food and air, and the epiglottis helps prevent food from entering the airways during swallowing. However, it is the esophagus that actively moves the food to the stomach.
