A nurse is reading a tuberculin skin test for a client who received a purified protein derivative test 72 hr ago. Which of the following findings indicates a positive test?
- A. An induration measuring 10 mm
- B. An induration measuring 5 mm
- C. A reddened area measuring 10 mm
- D. A reddened area measuring 5 mm
Correct Answer: A
Rationale: The correct answer is A: An induration measuring 10 mm. An induration of 10 mm or greater is considered a positive result for a tuberculin skin test in individuals who are at higher risk for tuberculosis. This indicates exposure to the tuberculosis bacteria and an immune response. Choices B, C, and D are incorrect because the presence of redness or a smaller induration size does not meet the criteria for a positive test result. Redness alone does not signify a positive result, and a smaller induration size is not indicative of a positive test. It is important to interpret tuberculin skin tests accurately to guide further testing and treatment decisions.

A nurse in an emergency department is caring for a 3-year-old child who has suspected epiglottitis. Which of the following actions should the nurse take?
- A. Prepare to assist with intubation.
- B. Obtain a throat culture.
- C. Suction the child's oropharynx.
- D. Prepare a cool mist tent
Correct Answer: A
Rationale: The correct answer is A: Prepare to assist with intubation. Epiglottitis is a medical emergency where the swelling of the epiglottis can rapidly obstruct the airway, leading to respiratory distress or failure. Intubation is crucial to secure the airway and ensure adequate oxygenation. Obtaining a throat culture (B) may delay necessary intervention. Suctioning the oropharynx (C) can trigger spasm and worsen the obstruction. Cool mist tent (D) does not address the immediate need for securing the airway.
A community health nurse is working with a family that is struggling to adapt following the loss of a family member. Which of the following actions should the nurse take first?
- A. Refer the family to a grief support group
- B. Determine the roles of individual family member
- C. Encourage the family to assign specific tasks to individual family members.
- D. Assist the family to establish a daily routine.
Correct Answer: B
Rationale: The correct answer is B: Determine the roles of individual family members. This should be the first action because understanding each family member's roles can help identify their needs, strengths, and how they can support each other. By determining roles, the nurse can establish a foundation for building effective coping strategies and addressing specific concerns within the family unit.
Incorrect choices:
A: Refer the family to a grief support group - This could be beneficial later on, but it's important to first understand the family dynamics and individual roles.
C: Encourage the family to assign specific tasks to individual family members - Assigning tasks may not address the underlying emotional needs of the family members.
D: Assist the family to establish a daily routine - While routines can be helpful, understanding roles is crucial for tailoring the routine to the family's specific situation.
Select the 5 actions the nurse should take.
- A. Increase the flowrate of the maintenance IV fluid
- B. Have the charge nurse notify the provider
- C. Place the client in a Trendelenburg position.
- D. Exert upward pressure on the presenting part.
- E. Attempt to push the umbilical cord back into the cervix
- F. Administer oxygen at 10 L/min via nonrebreather face mask
Correct Answer: B, C, D, E, F
Rationale: The correct actions (B, C, D, E, F) are based on managing a prolapsed umbilical cord during labor. B is crucial for timely intervention by involving the provider. C (Trendelenburg position) helps alleviate pressure on the cord. D (upward pressure) helps relieve compression on the cord. E aims to prevent cord compression. F (oxygen) supports fetal oxygenation. A is incorrect as increasing IV flowrate isn't a priority. G is not provided.
A nurse is conducting an initial assessment of a client and notices a discrepancy between the client's current IV infusion and the information received during the shift report. Which of the following actions should the nurse take?
- A. Contact the charge nurse to see if the prescription was changed
- B. Complete an incident report and place it in the client's medical record
- C. Submit a written warning for the nurse involved in the incident
- D. Compare the current infusion with the prescription in the client's medication record
Correct Answer: D
Rationale: The correct answer is D: Compare the current infusion with the prescription in the client's medication record. This is the best course of action as it allows the nurse to verify the accuracy of the IV infusion against the prescribed treatment plan. By cross-referencing the current infusion with the prescription in the client's medication record, the nurse can identify any discrepancies and take appropriate actions to ensure the client's safety and well-being.
Choice A is incorrect because contacting the charge nurse may not provide the necessary information to verify the accuracy of the IV infusion. Choice B is incorrect as completing an incident report is premature without first verifying the discrepancy. Choice C is inappropriate and punitive without a proper investigation. Choices E, F, and G are not provided in the question, so they are irrelevant.
A nurse is caring for a client who is in active labor and notes the FHR baseline has been 100/min for the past 15 min. The nurse should identify which of the following conditions as a possible cause of fetal bradycardia?
- A. Maternal hypoglycemia
- B. Chorioamnionitis
- C. Fetal anemia
- D. Maternal fever
Correct Answer: C
Rationale: Correct Answer: C (Fetal anemia)
Rationale: Fetal anemia can lead to decreased oxygen delivery to the fetus, causing fetal bradycardia. Anemia reduces the oxygen-carrying capacity of the blood, resulting in the heart working harder to compensate for the decreased oxygen levels, leading to a lower fetal heart rate.
Summary of Incorrect Choices:
A: Maternal hypoglycemia - Unlikely to cause fetal bradycardia directly.
B: Chorioamnionitis - Typically presents with maternal fever and tachycardia, not fetal bradycardia.
D: Maternal fever - Can cause fetal tachycardia, not bradycardia.
