Adult Health Nursing Study Guide Answers

Correct Answer: C

Rationale: In a critically ill patient admitted to the ICU with acute renal failure requiring renal replacement therapy (RRT), the healthcare team should prioritize the initiation of continuous renal replacement therapy (CRRT). CRRT is preferred in critically ill patients with hemodynamic instability as it allows for slow and continuous removal of solutes and fluids, making it a safer option compared to intermittent hemodialysis. CRRT can also provide better control of volume status and electrolyte imbalances over a longer period, which is beneficial in critically ill patients who are hemodynamically unstable. Peritoneal dialysis is not commonly used in the ICU setting for acute renal failure requiring RRT, and loop diuretics are not effective in treating acute renal failure. Temporary hemodialysis catheters may also be used, but CRRT is generally preferred in critically ill patients for better hemodynamic tolerance and control of solute and fluid removal.

Correct Answer: A

Rationale: The nurse sharing Mr. Steve's medical records with a group of visiting members of a medical mission team violates his right to expect that all communications and records pertaining to his care should be treated as confidential. Patient confidentiality is a fundamental ethical principle in healthcare that protects a patient's privacy and sensitive information. Sharing medical records without the patient's consent breaches this confidentiality and can lead to legal and ethical consequences. It is important for healthcare providers to maintain the confidentiality of patient information to uphold trust between patients and healthcare professionals.

Correct Answer: B

Rationale: In a pregnant woman presenting with severe abdominal pain and vaginal bleeding at 8 weeks gestation with a closed cervix, the most likely cause of these symptoms is a threatened abortion. A threatened abortion is a common complication of early pregnancy characterized by vaginal bleeding and lower abdominal pain without cervical dilation. The cervix remains closed, indicating that the pregnancy is still intact but at risk of potential miscarriage. Placenta previa typically presents with painless vaginal bleeding in the second or third trimester, whereas ectopic pregnancy usually presents with abdominal pain and vaginal bleeding in the setting of a closed cervix but is less likely at 8 weeks gestation. Gestational trophoblastic disease is a rare cause of vaginal bleeding in pregnancy and typically presents in the first trimester with signs of hyperemesis gravidarum, uterine enlargement, and elevated β-hCG levels.

Correct Answer: A

Rationale: Task A, obtaining special food for the patient when she requests it, can be delegated to the nursing assistant. This task involves simple assistance with gathering food items and does not require specific medical knowledge or interventions. Tasks B, C, and D involve more direct patient care and assessment, which should be performed by the nursing staff who have the necessary training and expertise to address the complexities of anorexia nervosa.

Correct Answer: A

Rationale: Signs such as using tissues to doorknobs suggest that the patient is unconsciously controlling unacceptable impulses or feelings. This behavior falls under the category of defense mechanisms, specifically displacement, where the individual redirects their emotions from a threatening target to a safer one. In this case, the patient may be experiencing anxiety or fear related to contamination or germs, leading them to use tissues to avoid touching doorknobs directly. It is a way for the patient to manage their underlying emotions, albeit unconsciously, through this compulsive behavior.
