What is the result of bariatric surgery as a therapy for morbid obesity?
- A. Reduced insulin sensitivity
- B. Increased insulin sensitivity
- C. Reduced lipolysis
- D. Increased lipolysis
Correct Answer: B
Rationale: Bariatric fix insulin sensitivity jumps, fat shrinks, glucose flows, not lipolysis shifts. Nurses cheer this, a chronic reset win.

Non modifiable risk factors for developing chronic illness include:
- A. Smoking and hypertension
- B. Sedentary lifestyle and diabetes
- C. Family history and socio-political factors
- D. Working/living conditions and stress
Correct Answer: C
Rationale: Non-modifiable risk factors are inherent traits or circumstances that cannot be changed, unlike modifiable factors tied to behavior or environment. Smoking and hypertension are modifiable through lifestyle changes or medical intervention, not fixed. Sedentary lifestyle is a choice, and diabetes, while influenced by genetics, is often manageable, making them modifiable. Family history, such as genetic predisposition to diseases like cancer or heart disease, is unalterable, and socio-political factors like access to healthcare shaped by policy or socioeconomic status are beyond individual control, fitting the non-modifiable category. Working and living conditions, plus stress, can be adjusted with resources or coping strategies, classifying them as modifiable. The distinction lies in control: family history and socio-political factors remain static, influencing chronic illness risk without personal alteration, as noted in foundational chronic disease literature like Farrell (2017), emphasizing genetics and societal context over mutable habits.
The nurse is caring for a client with mitral regurgitation. Which of the following would the nurse anticipate the client to develop if left untreated?
- A. Left-sided heart failure
- B. Right-sided heart failure
- C. Renal failure
- D. Myocardial ischemia
Correct Answer: A
Rationale: Mitral regurgitation backflows blood into the left atrium, hiking pressure and volume untreated, it overburdens the left ventricle, leading to left-sided heart failure. Pulmonary congestion follows, with dyspnea and edema, a direct consequence of this valve flaw. Right-sided failure stems from downstream effects or separate causes, not primary here. Renal failure or ischemia might complicate advanced disease, but left-sided failure's progression is the immediate risk, rooted in mitral dysfunction's mechanics. Nurses anticipate this, monitoring for early signs like crackles, ensuring timely intervention to halt this predictable cardiac cascade.
The nurse is admitting an oncology patient to the unit prior to surgery. The nurse reads in the electronic health record that the patient has just finished radiation therapy. With knowledge of the consequent health risks, the nurse should prioritize assessments related to what health problem?
- A. Cognitive deficits
- B. Impaired wound healing
- C. Cardiac tamponade
- D. Tumor lysis syndrome
Correct Answer: B
Rationale: Radiation pre-surgery zaps tissue impaired wound healing's the big risk, as it fries skin and vessels, slowing repair post-op. Cognitive deficits need brain radiation, not specified. Tamponade's rare, tied to chest radiation and fluid buildup. TLS hits post-chemo, not pre-surgery. Nurses in oncology lock onto skin checks and infection signs, knowing radiation's legacy can tank surgical outcomes if ignored.
A nurse sets an infusion pump to infuse 1 L of D5NS at the rate of $100 \mathrm{~mL} / \mathrm{hr}$. How many hours will it take to complete the infusion?
- A. 8
- B. 10
- C. 12
- D. 14
Correct Answer: B
Rationale: Math rules IV timing 1 L (1000 mL) at 100 mL/hr divides to 10 hours, a straightforward calc nurses nail for fluid planning. Missteps like 8 or 12 flub the rate; 14's way off. Precision here ensures hydration or med delivery hits the mark, a basic skill keeping care on track.
The nurse knows that hemolytic to blood transfusions occur most often when the first milliliters of the infusion.
- A. 125
- B. 50
- C. 100
- D. 75
Correct Answer: B
Rationale: Hemolytic reactions strike early 50 mL often triggers as mismatched blood clashes, a rapid antigen-antibody storm. Later volumes (75-125) build on it; 100's common but not peak. Nurses watch those first drops, stopping at 50 mL's hint of fever or pain, a tight window in this transfusion trap.
