HESI RN
HESI Leadership and Management
1. A nurse is preparing to administer NPH insulin to a client with DM. The nurse notes that the NPH insulin vial is cloudy. The nurse should:
- A. Obtain a new vial of NPH insulin.
- B. Draw up the cloudy insulin as ordered.
- C. Shake the vial vigorously before drawing up the insulin.
- D. Warm the insulin to room temperature before administration.
Correct answer: B
Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.
2. What is the most common cause of urinary tract infections (UTIs)?
- A. Escherichia coli infection
- B. Staphylococcus aureus infection
- C. Pseudomonas aeruginosa infection
- D. Klebsiella pneumoniae infection
Correct answer: A
Rationale: Escherichia coli is the most common cause of urinary tract infections (UTIs). It is responsible for the majority of UTIs, especially in women. E. coli is a normal inhabitant of the bowel and can enter the urinary tract through the urethra, leading to infection. Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae are less common causes of UTIs compared to E. coli. Staphylococcus aureus typically causes skin and soft tissue infections, Pseudomonas aeruginosa is more commonly associated with healthcare-associated infections, and Klebsiella pneumoniae is known for causing pneumonia and other respiratory infections.
3. An older client with SIRS has a temperature of 101.8°F, a heart rate of 110 beats per minute, and a respiratory rate of 24 breaths per minute. Which additional finding is most important to report to the healthcare provider?
- A. Serum creatinine of 2.0 mg/dL
- B. Elevated WBC count
- C. Blood pressure of 100/60 mmHg
- D. Oxygen saturation of 95%
Correct answer: A
Rationale: A serum creatinine level of 2.0 mg/dL indicates possible acute kidney injury, which can occur during severe systemic inflammatory response syndrome (SIRS). Reporting this value promptly allows for interventions to prevent further renal damage. Elevated WBC count (choice B) is a common feature of SIRS and may not be as urgently indicative of immediate organ damage as high creatinine levels. A blood pressure of 100/60 mmHg (choice C) is relatively low but may be a typical finding in SIRS; however, renal function is critical in this context. Oxygen saturation of 95% (choice D) is within normal limits and is not as concerning as a high creatinine level in this scenario.
4. A female client on a psychiatric unit is sweating profusely while vigorously doing push-ups and then running the length of the corridor several times before crashing into furniture in the sitting room. Picking herself up, she begins to toss chairs aside, looking for a red one to sit in. When another client objects to the disturbance, the client shouts, “I am the boss here. I do what I want.” Which nursing problem best supports these observations?
- A. Deficient diversional activity related to excess energy level.
- B. Disturbed personal identity related to grandiosity.
- C. Risk for activity intolerance related to hyperactivity.
- D. Risk for other-directed violence related to disruptive behaviors.
Correct answer: D
Rationale: The client's behavior of engaging in disruptive and aggressive actions, as well as claiming authority over others in the setting, indicates a risk for other-directed violence. This behavior poses a potential threat to the safety of others in the environment. Choice A is incorrect as the client's behavior is not solely indicative of a lack of diversional activities but rather a more serious issue. Choice B is incorrect as the behavior described does not primarily reflect disturbances in personal identity but rather displays of power and aggression. Choice C is incorrect as the client's actions do not suggest an intolerance to activity but rather an excessive and potentially harmful level of hyperactivity.
5. The nurse is caring for a client with hyperaldosteronism. Which of the following laboratory results would the nurse expect?
- A. Hypokalemia
- B. Hypernatremia
- C. Hyperkalemia
- D. Hypocalcemia
Correct answer: A
Rationale: In hyperaldosteronism, there is an excess of aldosterone production, leading to increased sodium retention and potassium excretion by the kidneys. This results in hypokalemia (low potassium levels). Therefore, the correct answer is hypokalemia (Choice A). Hypernatremia (Choice B) is an incorrect choice as hyperaldosteronism primarily affects potassium and not sodium levels. Hyperkalemia (Choice C) is also incorrect because hyperaldosteronism causes potassium excretion, leading to low levels. Hypocalcemia (Choice D) is not typically associated with hyperaldosteronism; instead, it is more related to conditions affecting calcium regulation.
