Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: A

Rationale: The presentation described is consistent with acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. On examination, the affected eye appears red, with a steamy cornea due to corneal edema and a mid-dilated, non-reactive pupil due to pupillary block from the forward displacement of the iris. Acute angle-closure glaucoma is considered a medical emergency as it can lead to permanent vision loss if not promptly treated. Prompt management involves reducing intraocular pressure to prevent further damage to the optic nerve.

Correct Answer: C

Rationale: If the nurse observes an unusual odor emanating from the surgical site during surgery, it is important to inform the surgeon immediately and assess for signs of infection. Changes in odor can sometimes be an early sign of infection, which requires prompt attention and intervention. By communicating with the surgeon and conducting a thorough assessment, the nurse can help ensure the timely detection and management of any potential complications, such as infection, that may be affecting the patient's surgical outcome. Prompt action in response to unusual observations is crucial to maintaining patient safety and well-being during surgical procedures.

Correct Answer: B

Rationale: The most appropriate action in this situation is to perform abdominal thrusts, also known as the Heimlich maneuver. This technique is used to clear a blocked airway caused by a choking obstruction. Encouraging continued coughing may not be effective if the person is unable to dislodge the obstruction on their own. Delivering back blows can sometimes be effective, but abdominal thrusts are more commonly recommended in cases of choking in adults. Administering rescue breaths is not recommended if the person is conscious and able to cough, as it may worsen the situation by pushing the obstruction further down. By quickly performing abdominal thrusts, you can help dislodge the obstruction and potentially save the person's life.

Correct Answer: B

Rationale: When communicating with a patient experiencing delirium, the nurse's priority is to provide clear and simple explanations to minimize confusion. Delirium can cause disorientation, confusion, and impaired cognitive function, making it difficult for the patient to understand complex information. Using simple language and clear explanations can help the patient better comprehend the situation and reduce anxiety. It is essential for the nurse to speak calmly, use reassuring gestures, and maintain a supportive presence to effectively communicate with a delirious patient. This approach can help establish a sense of trust and foster a therapeutic nurse-patient relationship during the challenging experience of delirium.

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.
