A nurse is caring for a 3-year-old child with strabismus. Which of the following actions should the nurse advise the parents to implement to help prevent amblyopia?
- A. Wear corrective biconcave lenses.
- B. Prevent trauma to the eyes.
- C. Patch the strong eye.
- D. Instill artificial tears.
Correct Answer: C
Rationale: The correct answer is C: Patch the strong eye. Patching the strong eye helps improve vision in the weaker eye, which is essential in preventing amblyopia. By covering the strong eye, the brain is forced to rely on the weaker eye, strengthening its visual acuity. Wearing corrective biconcave lenses may help with refractive errors but does not directly address amblyopia prevention. Preventing trauma to the eyes is important for overall eye health but does not specifically target amblyopia prevention. Instilling artificial tears is used for dry eye syndrome and does not play a role in preventing amblyopia.

Which is the recommended treatment for moderate to severe lead poisoning?
- A. IV fluids
- B. Antiemetics
- C. Heavy metal antagonist
- D. Antibiotics
Correct Answer: C
Rationale: The heavy metal antagonist, edetate calcium disodium, is frequently the drug of choice for the removal of the lead toxin from the body. Chelating agents inactivate the toxicity of the lead and cause excretion through the urine. IV fluids, antiemetics, and antibiotics do not address the core issue of removing lead from the body.
A 17-year-old client delivered her first baby 8 hours ago. Which of the following is an indication that appropriate bonding is occurring? The client:
- A. makes eye contact with the baby.
- B. wonders why the baby cries so much.
- C. asks the nurse to help change the baby's diaper.
- D. asks the nurse if the baby is cute.
Correct Answer: A
Rationale: The correct answer is A: makes eye contact with the baby. This indicates appropriate bonding as eye contact fosters emotional connection and attachment between mother and baby. It shows the mother is engaging with her child, seeking to establish a bond. Choice B suggests lack of understanding of infant communication, choice C indicates practical caregiving rather than emotional bonding, and choice D focuses on the baby's appearance rather than emotional connection.
A nurse in the antepartum clinic is assessing a client's adaptation to pregnancy. The client states that she is, ''happy one min and crying the next.'' The nurse should interpret the client's statement as an indication of which of the following?
- A. Emotional lability
- B. Focusing phase
- C. Cognitive restructuring
- D. Couvade syndrome
Correct Answer: A
Rationale: The correct answer is A: Emotional lability. Emotional lability refers to rapid, unpredictable changes in emotions. During pregnancy, hormonal fluctuations can lead to mood swings, causing the client to feel happy one minute and crying the next. Focusing phase (B) is not relevant to the client's emotional state. Cognitive restructuring (C) involves changing negative thought patterns, which is not mentioned in the scenario. Couvade syndrome (D) is a condition where male partners experience pregnancy-like symptoms, which is not applicable here.
A child diagnosed with asthma begins corticosteroid treatments. The nurse explains to the parents that the purpose of corticosteroid treatment is to produce which therapeutic effect?
- A. Dilation of bronchial airways
- B. Decrease bronchospasms
- C. Prevention of infection
- D. Anti-inflammatory effect
Correct Answer: D
Rationale: Corticosteroid usage is common for decreasing inflammation of the bronchial airways. While dilation of bronchial airways and decrease in bronchospasms are effects of other medications like albuterol and beta-2 agonists, corticosteroids specifically target inflammation, which is a key component in managing chronic asthma.
A nurse is caring for a client who is 36 weeks of gestation and has a prescription for an amniocentesis. For which of the following reasons should the nurse prepare the client for an ultrasound?
- A. To estimate fetal weight
- B. To locate a pocket of fluid
- C. To determine multiparity
- D. To pre-screen for fetal anomalies
Correct Answer: B
Rationale: The correct answer is B: To locate a pocket of fluid. Before performing an amniocentesis procedure, it is essential to locate a pocket of amniotic fluid to ensure the safety of the fetus during the procedure. This is crucial to avoid accidentally puncturing the fetus or placenta. An ultrasound helps in visualizing the amniotic fluid pocket and guiding the needle insertion accurately.
Incorrect Choices:
A: To estimate fetal weight - Estimating fetal weight is not a primary reason for preparing the client for an ultrasound before amniocentesis.
C: To determine multiparity - Multiparity (number of pregnancies) does not directly impact the need for an ultrasound before an amniocentesis.
D: To pre-screen for fetal anomalies - While ultrasounds can detect anomalies, the primary purpose before an amniocentesis is to locate the amniotic fluid pocket, not screen for anomalies.
