The removal of plasma water and some low–molecular weight particles by using a pressure or osmotic gradient is known as
- A. dialysis.
- B. diffusion.
- C. clearance.
- D. ultrafiltration.
Correct Answer: D
Rationale: Ultrafiltration is the correct answer because it involves the removal of plasma water and low-molecular weight particles by using a pressure or osmotic gradient. During ultrafiltration, the pressure gradient pushes the fluid through a semipermeable membrane, separating the substances based on their molecular size. This process allows for the selective removal of unwanted substances while retaining essential components. Dialysis (choice A) involves the removal of waste products from the blood, but it does not specifically target plasma water and low-molecular weight particles. Diffusion (choice B) is the passive movement of particles from an area of higher concentration to an area of lower concentration and is not specific to the removal of plasma water. Clearance (choice C) refers to the rate at which a substance is removed from the blood and does not involve the mechanism of pressure or osmotic gradient utilized in ultrafiltration.

A young man has just arrived at the ICU from out of town and received news that his girlfriend, who is admitted there, likely only has a few days left to live. Which of the following would be the best approach for the nurse to take in caring for the needs of this young man?
- A. Recommending that he go home and rest
- B. Giving him unrestricted visiting hours with the patient
- C. Suggesting that he meet with the hospital chaplain
- D. Recommending that he ask the doctor to evaluate the patients pain control measures
Correct Answer: C
Rationale: The correct answer is C: Suggesting that he meet with the hospital chaplain. This approach is best as it addresses the young man's emotional and spiritual needs during a difficult time. The chaplain can provide comfort, support, and guidance in coping with his girlfriend's situation. This option focuses on holistic care and acknowledges the importance of emotional well-being.
A: Recommending that he go home and rest is not the best approach as it dismisses the young man's emotional distress.
B: Giving him unrestricted visiting hours with the patient may not be appropriate as it can be overwhelming and may not address his emotional needs effectively.
D: Recommending that he ask the doctor to evaluate the patient's pain control measures is important but does not directly address the young man's emotional needs in this situation.
A client with asthma receives a prescription for high blood pressure during a clinic visit. Which prescription should the nurse anticipate the client to receive that is least likely to exacerbate asthma?
- A. Carteolol (Ocupress)
- B. Propranolol hydrochloride (Inderal)
- C. Pindolol (Visken)
- D. Metoprolol tartrate (Lopressor)
Correct Answer: D
Rationale: The correct answer is D, Metoprolol tartrate (Lopressor). Metoprolol is a cardioselective beta-blocker that primarily targets beta-1 receptors in the heart, making it less likely to exacerbate asthma compared to non-selective beta-blockers like Propranolol (choice B) and Pindolol (choice C). Carteolol (choice A) is also a non-selective beta-blocker and can potentially worsen asthma symptoms. Metoprolol's selectivity for beta-1 receptors minimizes bronchoconstriction, making it the safest choice for a client with asthma and high blood pressure.
Which statement is true regarding the impact of culture on end-of-life decision making?
- A. African-Americans prefer more conservative, less invaasbiirvbe.c ocma/rtees to ptions during the end of life.
- B. Caucasians prefer aggressive and more invasive care options during the end of life.
- C. Culture and religious beliefs may affect end-of-life decision making.
- D. Perspectives regarding end-of-life care are similar betwabeirebn.c oamn/dte swt ithin religious groups.
Correct Answer: C
Rationale: Rationale:
1. Culture and religious beliefs can significantly impact end-of-life decision making by influencing values, beliefs, and preferences.
2. These factors may affect choices related to treatment options, quality of life, and spiritual aspects.
3. Different cultural backgrounds may lead to varying perspectives on autonomy, family involvement, and medical interventions.
4. Option A and B make generalizations based on race, which is not accurate as preferences can vary widely within any racial group.
5. Option D is incorrect as perspectives on end-of-life care can vary even within the same religious group due to individual beliefs and interpretations.
Which strategy is important to addressing issues associated with the aging workforce? (Select all that apply.)
- A. Allowing nurses to work flexible shift durations
- B. Encouraging older nurses to transfer to an outpatient se tting that is less stressful
- C. Hiring nurse technicians that are available to assist wit h patient care, such as turning the patient
- D. Developing a staffing model that accurately reflects th e unit’s needs.
Correct Answer: A
Rationale: The correct answer is A: Allowing nurses to work flexible shift durations. This strategy is important in addressing issues associated with the aging workforce because it acknowledges the changing needs and preferences of older nurses. By offering flexible shift durations, older nurses can better manage their work-life balance, reduce physical strain, and continue contributing to the workforce effectively.
Choices B, C, and D are incorrect because they do not directly address the specific needs of the aging workforce. Encouraging older nurses to transfer to a less stressful outpatient setting may not align with their career goals. Hiring nurse technicians to assist with patient care may not address the unique experience and expertise of older nurses. Developing a staffing model, while important, does not specifically cater to the needs of aging nurses in terms of flexibility and support.
Ideally, by whom and when should an advance directive be developed?
- A. Family, if the patient is in critical condition.
- B. Patient as part of the hospital admission process.
- C. Patient before illness or impairment occurs.
- D. Patient’s healthcare surrogate.
Correct Answer: C
Rationale: Step-by-step rationale for choice C:
1. Advance directives should be made by the patient to reflect their wishes.
2. Developing it before illness ensures clarity and avoids confusion.
3. Patients may not be able to make informed decisions in critical conditions.
4. Family or surrogates may not accurately represent the patient's wishes.
Summary:
A - Family in critical condition may not know the patient's wishes.
B - Hospital admission process may be too late for clear decision-making.
D - Healthcare surrogate may not fully understand the patient's preferences.
