1. The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?
- A. triglyceride level
- B. liver function tests
- C. a glucose tolerance test
- D. a complete blood count
Correct answer: B
Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (Choice A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (Choice C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (Choice D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.
2. The nurse teaching about preventable diseases should emphasize the importance of getting the following vaccines:
- A. human papillomavirus, genital herpes, measles.
- B. pneumonia, HIV, mumps.
- C. syphilis, gonorrhea, pneumonia.
- D. polio, pertussis, measles.
Correct answer: D
Rationale: Vaccines are one of the most effective methods of preventing and controlling certain communicable diseases. The smallpox vaccine is not currently in use because the smallpox virus has been declared eradicated from the world's population. Diseases such as polio, diphtheria, pertussis, and measles are mostly controlled by routine childhood immunization. They have not, however, been eradicated, so children need to be immunized against these diseases. Choices A, B, and C contain vaccines that do not protect against preventable diseases like polio, pertussis, and measles. Therefore, the correct choice is D.
3. Which of the following injuries, if demonstrated by a client entering the Emergency Department, is the highest priority?
- A. open leg fracture
- B. open head injury
- C. stab wound to the chest
- D. traumatic amputation of a thumb
Correct answer: C
Rationale: A stab wound to the chest might result in lung collapse and mediastinal shift that, if untreated, could lead to death. Treatment of an obstructed airway or a chest wound is a higher priority than hemorrhage. The principle of ABC (airway, breathing, and circulation) prioritizes care decisions. In this scenario, the stab wound to the chest poses the highest risk to the client's life as it can lead to severe complications such as lung collapse and mediastinal shift. Addressing this injury promptly is crucial to prevent further harm or potential fatality. Open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate life-threatening risk compared to a stab wound to the chest.
4. Which symptoms is the client who overdosed on barbiturates most likely to exhibit?
- A. Bradypnea and bradycardia
- B. Hyperthermia and drowsiness
- C. Hyperreflexia and slurred speech
- D. Tachycardia and psychosis
Correct answer: A
Rationale: The correct answer is bradypnea and bradycardia. Barbiturates are central nervous system (CNS) depressants, which will slow down the respiratory rate (bradypnea) and heart rate (bradycardia). Choice B, hyperthermia and drowsiness, is incorrect as barbiturate overdose typically does not cause hyperthermia but rather hypothermia. Hyperreflexia and slurred speech (Choice C) are more indicative of stimulant overdoses rather than CNS depressants like barbiturates. Tachycardia and psychosis (Choice D) are also not typically seen in barbiturate overdose, as these drugs tend to depress the CNS rather than cause symptoms of increased heart rate or psychosis.
5. Jane Love, a 35-year-old gravida III para II at 23 weeks gestation, is seen in the Emergency Department with painless, bright red vaginal bleeding. Jane reports that she has been feeling tired and has noticed ankle swelling in the evening. Laboratory tests reveal a hemoglobin level of 11.5 g/dL. After evaluating the situation, the nurse determines that Jane is at risk for placenta previa, based on which of the following data?
- A. anemia
- B. edema
- C. painless vaginal bleeding
- D. fatigue
Correct answer: C
Rationale: Placenta previa is a disorder where the placenta implants in the lower uterine segment, causing painless bleeding in the third trimester of pregnancy. The bleeding results from tearing of the placental villi from the uterine wall as the lower uterine segment contracts and dilates. It can be slight or profuse and can include bright red, painless bleeding. While anemia (choice A) may be a consequence of chronic bleeding from placenta previa, it is not a direct indicator. Edema (choice B) and fatigue (choice D) are nonspecific symptoms that can occur in pregnancy but are not specific to placenta previa.
