1. The parents of a 9-month-old infant are being educated about preventing iron deficiency anemia. Which statement by the parent indicates a correct understanding of the teaching?
- A. I will start giving my baby whole cow’s milk at 12 months
- B. I will give my baby iron-fortified cereal
- C. I will give my baby fruit juice between meals
- D. I will give my baby water with meals
Correct answer: B
Rationale: The correct answer is B: 'I will give my baby iron-fortified cereal.' Iron-fortified cereal is an excellent source of iron for infants, aiding in the prevention of iron deficiency anemia. Choice A is incorrect as whole cow’s milk should not be introduced until the child is at least 12 months old to prevent iron deficiency. Choice C is incorrect because giving fruit juice between meals can interfere with iron absorption. Choice D is incorrect as giving water with meals can decrease nutrient intake. Therefore, the best choice to prevent iron deficiency anemia in a 9-month-old infant is to give them iron-fortified cereal.
2. A client who developed syndrome of inappropriate antidiuretic hormone (SIADH) associated with small carcinoma of the lung is preparing for discharge. When teaching the client about self-management with demeclocycline (Declomycin), the nurse should instruct the client to report which condition to the healthcare provider?
- A. Insomnia
- B. Muscle cramping
- C. Increased appetite
- D. Anxiety
Correct answer: B
Rationale: The correct answer is B: Muscle cramping. SIADH causes dilutional hyponatremia due to increased ADH release. Demeclocycline is used to block the action of ADH. Muscle cramping can indicate electrolyte imbalances related to hyponatremia, which should be reported to the healthcare provider. Insomnia, increased appetite, and anxiety are not typically associated with the side effects or complications of demeclocycline or SIADH.
3. When another nurse enters the room in response to a call, after checking the client's pulse and respirations during CPR on an adult in cardiopulmonary arrest, what should be the function of the second nurse?
- A. Relieve the nurse performing CPR
- B. Go get the code cart
- C. Participate with the compressions or breathing
- D. Validate the client's advanced directive
Correct answer: C
Rationale: The correct answer is to participate in compressions or breathing. This is essential to ensure continuous and effective CPR. Relieving the nurse performing CPR (Choice A) is not recommended as it can interrupt the life-saving procedure. Going to get the code cart (Choice B) may be necessary in certain situations but should not take precedence over providing immediate assistance in CPR. Validating the client's advanced directive (Choice D) is not the primary role in this scenario where urgent action is needed to support the client's circulation and breathing.
4. When caring for a client with a chest tube, which intervention is most important?
- A. Keep the drainage system at chest level.
- B. Ensure that the chest tube is clamped at all times.
- C. Strip the chest tube every shift.
- D. Ensure that the chest tube is connected to a water-seal drainage system.
Correct answer: D
Rationale: The most crucial intervention when caring for a client with a chest tube is to ensure that the chest tube is connected to a water-seal drainage system (D). This system helps maintain proper lung expansion and prevents complications. Keeping the drainage system at chest level (A) is important to facilitate drainage, but not as critical as ensuring the connection to the drainage system. Clamping the chest tube (B) is unnecessary and can lead to serious issues. Stripping the chest tube (C) is an outdated practice and can cause harm rather than benefit.
5. The healthcare provider is assessing a client with chronic renal failure who is receiving hemodialysis. Which of the following findings would indicate a complication of the treatment?
- A. Temperature of 98.6°F (37°C).
- B. Weight gain of 2 lbs (0.9 kg) since the last treatment.
- C. Blood pressure of 130/80 mm Hg.
- D. Pulse rate of 72 bpm.
Correct answer: B
Rationale: Weight gain between dialysis sessions can indicate fluid overload, a common complication in clients with chronic renal failure. This can lead to complications such as hypertension, pulmonary edema, and heart failure. A normal temperature, blood pressure, and pulse rate are expected findings in this scenario and would not typically indicate a complication of hemodialysis treatment.
