A nurse on a pediatric unit is assigned to care for a child with Reye syndrome. Which of the following is the most serious clinical manifestation for which the nurse should monitor?
- A. Anaphylaxis
- B. Cerebral edema
- C. Impaired coagulation
- D. Hypervolemia
Correct Answer: B
Rationale: The correct answer is B: Cerebral edema. In Reye syndrome, cerebral edema is the most serious manifestation due to increased intracranial pressure, potentially leading to brain damage or death. Anaphylaxis (A) is not typically associated with Reye syndrome. Impaired coagulation (C) can occur but is not as immediately life-threatening as cerebral edema. Hypervolemia (D) is a possible complication but not as critical as cerebral edema in Reye syndrome.

A nurse is reinforcing teaching to a group of parents about preventing accidental poisoning in preschoolers. Which of the following should the nurse include?
- A. Have syrup of ipecac available in the home.
- B. Explain to preschool children that plants can be eaten only after they are cooked.
- C. Keep labels on containers of toxic substances and never remove them.
- D. Place medications in a cabinet above the sink.
Correct Answer: C
Rationale: The correct answer is C: Keep labels on containers of toxic substances and never remove them. This is important to prevent accidental poisoning in preschoolers as it helps parents and caregivers easily identify and differentiate toxic substances from safe ones. Removing labels can lead to confusion and increase the risk of accidental ingestion. Having syrup of ipecac available (choice A) is no longer recommended as a first-aid treatment for poisoning. Teaching children to cook plants before eating them (choice B) is not a practical or safe approach. Placing medications in a cabinet above the sink (choice D) may not be effective as preschoolers can still access them if the cabinet is not securely locked.
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.
For a client in the second trimester of pregnancy, which assessment data support a diagnosis of pregnancy-induced hypertension (PIH)?
- A. Hemoglobin 10.2 mg/dL and uterine tenderness
- B. Polyuria and weight loss of 3 pounds in the last month
- C. Blood pressure 168/110 and 3+ proteinuria
- D. Hematuria and blood glucose of 160 mg/dL
Correct Answer: C
Rationale: The correct answer is C: Blood pressure 168/110 and 3+ proteinuria. Pregnancy-induced hypertension (PIH) is characterized by high blood pressure (systolic ≥140 mmHg and/or diastolic ≥90 mmHg) and proteinuria. In this case, the blood pressure reading of 168/110 indicates hypertension, and 3+ proteinuria indicates significant protein in the urine, both of which are key diagnostic criteria for PIH.
A: Hemoglobin 10.2 mg/dL and uterine tenderness - These are not specific indicators of PIH.
B: Polyuria and weight loss of 3 pounds in the last month - These symptoms are not typically associated with PIH.
D: Hematuria and blood glucose of 160 mg/dL - Hematuria suggests blood in the urine, which is not a typical finding in PIH, and elevated blood glucose is more indicative of diabetes rather than PIH.
Therefore,
If a pregnant client diagnosed with gestational diabetes cannot maintain control of her blood sugar by diet alone, which medication will she receive?
- A. Metformin (Glucophage)
- B. Glucagon
- C. Insulin
- D. Glyburide (DiaBeta)
Correct Answer: C
Rationale: The correct answer is C: Insulin. Insulin is the preferred medication for managing gestational diabetes as it is safe for the fetus and provides precise blood sugar control. Metformin (A) and Glyburide (D) are alternatives if insulin is not tolerated, but they may cross the placenta and have potential risks. Glucagon (B) is not used for diabetes management but for treating severe hypoglycemia.
A client asks the nurse about the benefits of breastfeeding. Which response by the nurse provides the most accurate information?
- A. Breastfeeding helps women lose weight faster.
- B. Breast milk contains a greater amount of protein.
- C. Breast milk is easier to digest than formula.
- D. Breastfeeding is a good method of contraception.
Correct Answer: C
Rationale: The correct answer is C: Breast milk is easier to digest than formula. Breast milk contains specific enzymes and antibodies that aid in digestion and are easily absorbed by the baby's immature digestive system. This promotes better nutrient absorption and reduces the risk of digestive issues. Option A is incorrect because weight loss varies for each woman and should not be the primary reason for breastfeeding. Option B is incorrect as breast milk has a balanced composition of nutrients, not just higher protein content. Option D is incorrect as breastfeeding is not a reliable form of contraception.
