Nclex Exam Cram Practice Questions
1. How many temporary teeth should the nurse expect to find in a 5-year-old client's mouth?
- A. up to 10
- B. up to 15
- C. up to 20
- D. up to 32
Correct answer: C
Rationale: A 5-year-old child can have up to 20 temporary (deciduous or baby) teeth. The first tooth usually erupts by age 6 months, and the last by age 30 months. All temporary teeth are usually shed between 6 and 13 years of age. Therefore, a 5-year-old child should have up to 20 temporary teeth. The correct answer is 'up to 20.' Choices A, B, and D are incorrect because the correct number of temporary teeth in a 5-year-old child's mouth is up to 20, not 10, 15, or 32.
2. 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.
3. Which of the following tests is commonly performed on newborns with jaundice?
- A. blood urea nitrogen
- B. magnesium
- C. bilirubin
- D. prolactin
Correct answer: C
Rationale: The correct answer is C: bilirubin. A high bilirubin level is found in newborns with hepatic immaturity, leading to jaundice. Testing bilirubin levels is crucial in diagnosing and monitoring jaundice in newborns. Choices A, B, and D (blood urea nitrogen, magnesium, and prolactin) are not commonly performed tests for evaluating jaundice in newborns. Blood urea nitrogen is a measure of kidney function, magnesium levels are usually checked in metabolic disorders, and prolactin is a hormone related to lactation, none of which are directly relevant to assessing jaundice in newborns.
4. A client is having a seizure; his blood oxygen saturation drops from 92% to 82%. What should the nurse do first?
- A. Open the airway.
- B. Administer oxygen.
- C. Suction the client.
- D. Check for breathing.
Correct answer: A
Rationale: When a client is having a seizure and their blood oxygen saturation drops significantly, the priority action for the nurse is to open the airway. This allows for adequate oxygenation and ventilation. Administering oxygen can come after ensuring the airway is clear. Suctioning the client should be done if there is an airway obstruction, and checking for breathing is part of the assessment but opening the airway takes precedence to ensure proper oxygenation and ventilation during a critical event like a seizure.
5. Ethics committees typically do not handle which of the following issues?
- A. Nonpayment of bills.
- B. Euthanasia.
- C. Starting or stopping treatment.
- D. Use of feeding tubes.
Correct answer: A
Rationale: Ethics committees primarily focus on addressing ethical dilemmas in healthcare. Issues like euthanasia, decisions regarding starting or stopping treatment, and the use of feeding tubes for nutritional support involve complex ethical considerations related to patient care and end-of-life decisions, which are commonly deliberated by ethics committees. However, nonpayment of bills is a financial matter and falls outside the typical scope of ethics committees' functions.
