1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. Which of the following conditions may warrant a serum creatinine level?

Correct answer: D

Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.

3. Which of the following conditions may cause an increased respiratory rate?

Correct answer: D

Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen. Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.

4. Which technological advance is MOST likely to place you at risk for HIPAA violations?

Correct answer: A

Rationale: The correct answer is Social media. Social media platforms such as Facebook can significantly put you at risk for HIPAA violations. It is crucial to never share any patient-related information or comments on social media websites, as this breaches patient confidentiality and violates HIPAA regulations. Choices B, C, and D are less likely to directly lead to HIPAA violations. Word processing programs and spreadsheets are commonly used for documentation and data organization, focusing more on internal operations and not on external sharing of sensitive information that can compromise patient confidentiality. Cloud storage services (Clouds and SOEs) are designed for secure data storage and sharing within regulated environments, and HIPAA compliance can be maintained if used appropriately. However, social media's open and unsecured nature makes it a higher risk for HIPAA violations compared to the other technological advances mentioned.

5. You are on the unit and overhear another nurse talking on the phone to a patient's friend who wants to see her patient who is comatose and on a ventilator. Since you cared for that patient yesterday, you know that the patient's significant other, who is also the designated healthcare surrogate (HCS) and has power of attorney (POA), has expressly stated that he wants this person on the list for restricted visitors. The nurse whispers that she'll call him to visit as soon as the significant other has gone home. What should your first response be?

Correct answer: C

Rationale: Speaking with the nurse directly and privately is the most constructive manner in which to handle this situation and advocate for the significant other's wishes. Doing so will open communication with a peer and build the relationship, instead of alienating the other nurse by taking action that does not involve her and will cast her in a negative light with others. It is essential to express your concerns regarding honoring the significant other's requests and rights regarding the limitation of visitors. Option A is incorrect because the significant other is not the one trying to visit, and it is more appropriate to address the nurse directly first. Option B is not the best initial response as it may escalate the situation without giving the nurse a chance to correct the issue. Option D is incorrect as it does not address the issue at its source and may create further conflict without resolving the underlying problem.
