Nursing Elites

1. Which hormone in the urine is specifically indicative of pregnancy?

• A. estrogen
• B. progesterone
• C. testosterone
• D. human chorionic gonadotropin

Correct answer: D

Rationale: Human chorionic gonadotropin is the hormone specifically indicative of pregnancy as it is produced by the placenta after implantation. It can be detected in urine and blood samples to confirm pregnancy. Estrogen and progesterone play crucial roles in the menstrual cycle and pregnancy but are not specific indicators of pregnancy on their own. Testosterone is a hormone primarily associated with male reproductive functions and is not directly related to pregnancy, making it an incorrect choice in this context.

2. When removing a client's gown with an intravenous line, what should the nurse do?

• A. temporarily disconnect the intravenous tubing at a point close to the client and thread it through the gown
• B. cut the gown with scissors
• C. thread the bag and tubing through the gown sleeve, keeping the line intact
• D. temporarily disconnect the tubing from the intravenous container and thread it through the gown

Correct answer: C

Rationale: The correct action when removing a client's gown with an intravenous line is to thread the bag and tubing through the gown sleeve while keeping the line intact. This method ensures that the system remains sterile and reduces the risk of infection. Temporarily disconnecting the tubing at a point close to the client or from the container introduces the potential for contamination. Cutting the gown with scissors should only be done in emergencies as it is not a standard practice and can compromise the integrity of the intravenous line. Therefore, the most appropriate and safe method is to thread the bag and tubing through the gown sleeve.

3. Which of these statements is true regarding advance directives?

• A. They must be reviewed and re-signed every 10 years in order to remain valid.
• B. An advance directive is legally valid in every state, regardless of the state it was created in.
• C. A physician must determine when a client is unable to make medical decisions for themselves.
• D. They cannot be honored by EMTs (emergency medical technicians) unless signed by a doctor.

Correct answer: D

Rationale: The correct statement is that advance directives cannot be honored by EMTs unless they are signed by a doctor. EMTs are required to provide emergency care to a client, irrespective of their advance directive status, unless the directive has been signed by a doctor. When a client is brought to the hospital, physicians will assess the client and implement the advance directive if necessary. Advance directives do not need to be reviewed and re-signed every 10 years to remain valid; they remain in effect until changed. While advance directives are legally valid in most states, some states may not honor those created in other states, so it's advisable to check the new state's policies if a client moves. Additionally, it typically requires two physicians, not just one, to determine if a client is unable to make medical decisions for themselves.

4. The graduate licensed practical nurse is assigned to care for the client on ventilator support, pending organ donation. Which goal should receive priority?

• A. Maintain the client's systolic blood pressure at 70mmHg or greater
• B. Maintain the client's urinary output greater than 300cc per hour
• C. Maintain the client's body temperature above 33�F rectal
• D. Maintain the client's hematocrit below 30%

Correct answer: A

Rationale: When caring for a client on ventilator support pending organ donation, maintaining the systolic blood pressure at 70mmHg or greater is crucial to ensure a proper blood supply to the donor organ. This goal is a priority to maintain the viability of the organ for donation. Choices B, C, and D are incorrect because they are unnecessary and not directly related to the immediate goal of organ donation. Maintaining urinary output, body temperature, or hematocrit levels are not the primary concerns in this situation.

5. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

• A. blood urea nitrogen
• B. serum calcium
• C. serum ammonia
• D. serum creatinine

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.
