Which of the following interventions is necessary before insertion of an arterial line into the radial artery?
- A. Ensure that the client does not need surgery
- B. Assess the client's grip strength
- C. Perform an Allen test
- D. Check a serum potassium level
Correct Answer: C
Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line.
Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.

A client in labor has an electronic fetal monitor attached to the abdomen, and the nurse notes that the baby's heart rate slows down during each contraction, returning to normal limits only after the contraction is complete. Which type of fetal heart rate change does this pattern describe?
- A. Variable decelerations
- B. Late decelerations
- C. Early decelerations
- D. Accelerations
Correct Answer: B
Rationale: Late decelerations refer to a pattern where the baby's heart rate decreases during contractions and does not return to normal until after the contraction ends. This is considered a non-reassuring sign as it indicates potential fetal distress. Late decelerations are associated with uteroplacental insufficiency, and immediate medical attention is required. Variable decelerations (Choice A) are abrupt, unpredictable decreases in the fetal heart rate, usually associated with cord compression. Early decelerations (Choice C) are usually benign and mirror the contraction pattern. Accelerations (Choice D) are reassuring signs of fetal well-being, characterized by an increase in the fetal heart rate.
The community health nurse has reviewed information about the population of a local community and has determined that there are groups in the population that are at high risk for infection with tuberculosis (TB). The nurse targets which high-risk group for screening?
- A. French Canadians
- B. White, Anglo-Saxon Americans
- C. Older clients in long-term-care facilities
- D. Adolescents between the ages of 13 and 17 years
Correct Answer: C
Rationale: Older clients in long-term-care facilities are at high risk for TB due to age-related immune decline and close living conditions. French Canadians, White Anglo-Saxon Americans, and adolescents are not specifically high-risk groups unless other factors apply.
The nurse is discussing concerns the parent has with his 3-year-old. The parent identifies limitations in the child's activities. Select all that should be of concern to the nurse.
- A. unable to work simple toys
- B. unable to understand simple instructions
- C. unable to say first and last name
- D. unable to name any colors or numbers
Correct Answer: A,B,D
Rationale: By age 3, children should manipulate simple toys, follow simple instructions, and name some colors or numbers. These limitations (A, B, D) suggest developmental delays requiring further evaluation. Saying first and last name (C) is less critical at this age.
The nurse is teaching a client about dietary modifications to control hypertension. Which statement by the client indicates a need for further teaching?
- A. I can have a cup of fresh fruit as a snack.
- B. Baked ham is a good dinner choice for me.
- C. I need to check the label for sodium in ketchup.
- D. I need to cut out frozen pizza as a fast meal option.
Correct Answer: B
Rationale: Baked ham is high in sodium, which is unsuitable for hypertension. Other choices align with low-sodium dietary recommendations.
Mrs. M has had diabetes for seven years. She has worked hard to control her blood glucose levels and watch her dietary intake. Her physician orders a hemoglobin A1C test. Which of the following best describes the action of this test?
- A. The test determines if the client is anemic and needs iron supplements
- B. The test determines if there is excess glucose building up in the urine
- C. The test determines the amount of hemoglobin reaching the liver to support gluconeogenesis
- D. The test determines the amount of hemoglobin that is coated with glucose
Correct Answer: D
Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.
