Nursing Elites

1. Which of the following neurological disorders is characterized by writhing, twisting movements of the face and limbs?

• A. epilepsy
• B. Parkinson's
• C. multiple sclerosis
• D. Huntington's chorea

Correct answer: D

Rationale: Huntington's chorea is a neurological disorder characterized by writhing, twisting movements of the face and limbs, known as chorea. Epilepsy is characterized by seizures, not writhing, twisting movements. Parkinson's disease presents with tremors, rigidity, and bradykinesia, not writhing, twisting movements. Multiple sclerosis affects the central nervous system but does not typically involve writhing, twisting movements. Therefore, the correct answer is Huntington's chorea as it specifically manifests with these characteristic movements.

2. A 10-year-old boy has been diagnosed with a congenital heart defect. Which of the following clinical signs does not indicate CHF?

• A. Increased body weight
• B. Elevated heart rate
• C. Lower extremity edema
• D. Compulsive behavior

Correct answer: D

Rationale: Compulsive behavior is not a clinical sign typically associated with congestive heart failure (CHF). CHF commonly presents with symptoms such as increased body weight due to fluid retention, elevated heart rate as the heart works harder to pump blood effectively, and lower extremity edema caused by fluid buildup. While behavioral changes can occur in response to illness, compulsive behavior is not a typical indicator of CHF. Choices A, B, and C are more commonly linked to CHF and should be monitored in patients with this condition.

3. A client with a closed chest tube drainage system accidentally disconnects the chest tube while being turned by the nurse. What should the nurse do first?

• A. Submerge the end of the chest tube in a bottle of sterile water
• B. Clamp the chest tube with a Kelly clamp
• C. Call the health care provider
• D. Instruct the client to inhale and hold his breath

Correct answer: A

Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.

4. 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.

5. The healthcare provider sustains a needle puncture that requires HIV prophylaxis. Which of the following medication regimens should be used?

• A. an antibiotic such as Metronidazole and a protease inhibitor (Saquinavir)
• B. two non-nucleoside reverse transcriptase inhibitors
• C. one protease inhibitor such as Nelfinavir
• D. two protease inhibitors

Correct answer: B

Rationale: In the scenario of a needle puncture requiring HIV prophylaxis, the CDC recommends initiating treatment with two non-nucleoside reverse transcriptase inhibitors, unless there is drug resistance. This regimen is preferred over other options such as a single protease inhibitor or two protease inhibitors due to its effectiveness and safety profile in this specific context. Non-nucleoside reverse transcriptase inhibitors are commonly used in post-exposure prophylaxis due to their activity against HIV and lower risk of resistance development compared to other antiretroviral drug classes.
