Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: A

Rationale: Patients with COPD are at increased risk for developing ventilator-induced lung injury (VILI) due to their underlying lung pathology. Using a low tidal volume strategy (6-8 ml/kg predicted body weight) has been shown to reduce the risk of VILI in these patients. Additionally, applying high positive end-expiratory pressure (PEEP) helps to recruit collapsed alveoli, improve oxygenation, and decrease the risk of barotrauma by keeping the alveoli open throughout the respiratory cycle. Therefore, the most appropriate ventilator settings to minimize the risk of VILI in a COPD patient with acute exacerbation and respiratory failure requiring mechanical ventilation would be low tidal volume and high PEEP.

Correct Answer: C

Rationale: Type 2 diabetes mellitus is characterized by insulin resistance in the peripheral tissues and defective beta cell secretion with loss of insulin. In type 2 diabetes, there is typically not destruction of beta cells from an autoimmune mechanism that leads to lack of insulin and hyperglycemia as seen in type 1 diabetes mellitus. Instead, in type 2 diabetes, the pancreas initially produces insulin, but the body's cells become resistant to its effects. This results in hyperglycemia due to the inability of the body to properly regulate blood sugar levels. Therefore, choice C is not true for type 2 diabetes mellitus.

Correct Answer: A

Rationale: The priority nursing action for a woman diagnosed with uterine rupture during labor is to prepare for immediate cesarean section. Uterine rupture is a serious obstetric emergency that can lead to severe maternal and fetal complications, including hemorrhage, fetal distress, and injury to both mother and baby. A cesarean section is necessary to deliver the baby promptly and address any potential complications, such as controlling bleeding and ensuring the safety of both the mother and the baby. Time is critical in these situations, and prompt surgical intervention is essential to optimize outcomes. Administering intravenous oxytocin or assisting the mother into a hands-and-knees position would not address the immediate risks associated with uterine rupture. Initiating cardiopulmonary resuscitation (CPR) is only necessary if the mother's condition deteriorates to the point of cardiac or respiratory arrest, which may occur as a result of significant hemorrhage or other complications associated with uterine

Correct Answer: A

Rationale: Illiterate clients may have difficulty understanding spoken or written information. Using symbols and images can help convey important messages and instructions in a visual way that can be easily understood without relying on literacy skills. This communication intervention is effective in ensuring that the client understands the information being provided, promoting better adherence to treatment plans and overall health outcomes.

Correct Answer: B

Rationale: CPAP therapy is considered the gold standard treatment for obstructive sleep apnea (OSA) and is the most appropriate intervention for managing OSA and improving symptoms. CPAP therapy involves using a machine that delivers a continuous flow of air through a mask worn over the nose or mouth during sleep. This air pressure helps keep the airway open, preventing the collapse that causes apneas and snoring during sleep.
