Nokea
The nurse is assessing a client with left-sided heart failure. Which clinical finding requires immediate intervention?
- A. Jugular venous distention
- B. Shortness of breath
- C. Crackles in the lungs
- D. Peripheral edema
Correct Answer: C
Rationale: Corrected Rationale: In a client with left-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention to prevent worsening heart failure symptoms and respiratory distress. Jugular venous distention, shortness of breath, and peripheral edema are also common in heart failure but are not as critical as crackles in the lungs because they may indicate fluid overload or right-sided heart failure, which are important to address but not as urgently as managing pulmonary congestion.

The nurse is caring for a client with a history of myocardial infarction who is experiencing chest pain. Which intervention should the nurse implement first?
- A. Administer oxygen therapy as prescribed.
- B. Obtain an electrocardiogram (ECG).
- C. Administer nitroglycerin sublingually as prescribed.
- D. Administer aspirin as prescribed.
Correct Answer: A
Rationale: Administering oxygen therapy is the priority intervention in managing chest pain in a client with a history of myocardial infarction. Oxygen helps improve oxygenation to the heart muscle, which is crucial in reducing further damage. Obtaining an electrocardiogram (ECG) is important to assess for changes indicative of myocardial infarction, but providing oxygen takes precedence as it directly addresses the physiological need for oxygen. Administering nitroglycerin and aspirin are important interventions but are typically implemented after oxygen therapy to address vasodilation and antiplatelet effects, respectively.
The healthcare provider prescribes ceftazidime (Fortaz) 35 mg every 8 hours IM for an infant. The 500 mg vial is labeled with the instruction to add 5.3 ml diluent to provide a concentration of 100 mg/ml. How many ml should the nurse administer for each dose?
- A. 0.35 ml
- B. 0.40 ml
- C. 0.50 ml
- D. 0.45 ml
Correct Answer: B
Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.
When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?
- A. Avoid administration of oxygen at high levels for extended periods.
- B. Increase oxygen flow rate if the child is still tachypneic.
- C. Reduce oxygen levels gradually after symptoms improve.
- D. Humidify the oxygen to prevent drying of mucous membranes.
Correct Answer: A
Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.
A client with a history of severe rheumatoid arthritis is receiving a corticosteroid. Which assessment finding should the nurse report to the healthcare provider immediately?
- A. Blood glucose level of 180 mg/dL
- B. Weight gain of 2 pounds in 24 hours
- C. Blood pressure of 140/90 mmHg
- D. Increased joint pain
Correct Answer: C
Rationale: Elevated blood pressure (140/90 mmHg) is a significant finding that the nurse should report immediately. Hypertension can be a severe side effect of corticosteroid therapy, especially in clients with preexisting conditions like rheumatoid arthritis. It requires prompt intervention to prevent complications such as cardiovascular events. The other options, while important to monitor, are not as critical as elevated blood pressure in this context. A blood glucose level of 180 mg/dL may indicate hyperglycemia, weight gain could be due to fluid retention, and increased joint pain is expected in a client with severe rheumatoid arthritis.
A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which intervention should the nurse implement first?
- A. Administer oxygen therapy as prescribed.
- B. Elevate the head of the bed.
- C. Assess the client's level of consciousness.
- D. Obtain a sputum culture.
Correct Answer: A
Rationale: Administering oxygen therapy as prescribed is the initial priority when managing an exacerbation of COPD. In COPD exacerbations, the primary concern is hypoxemia due to impaired gas exchange. Administering oxygen helps to improve oxygenation and prevent further complications. Elevating the head of the bed can aid in breathing comfort but is not the priority over ensuring adequate oxygen supply. Assessing the client's level of consciousness is important but comes after ensuring oxygenation. Obtaining a sputum culture is relevant for identifying pathogens but is not the immediate priority in addressing hypoxemia.
