Correct Answer: C

Rationale: In a tension pneumothorax, the trachea deviates to the unaffected side due to increased pressure in the affected pleural space, causing respiratory distress. Dyspnea is a hallmark symptom as the lung on the affected side collapses, leading to difficulty in breathing. Sudden hypertension and bradycardia (Choice A) are not typical findings of tension pneumothorax. Productive cough with yellow mucus (Choice B) is more suggestive of respiratory infections rather than a tension pneumothorax. Sudden development of profuse hemoptysis and weakness (Choice D) is not characteristic of tension pneumothorax presentation.

Correct Answer: C

Rationale: Prior to an EEG, it is essential for the client to eat to prevent a drop in blood sugar levels. The nurse should hold sedatives but allow the client to have breakfast and administer other necessary medications. Holding sedatives is crucial to ensure accurate EEG results, while providing breakfast helps maintain stable blood sugar levels. Administering other medications, excluding sedatives, is important for the client's overall care. Choices A, C, and D are incorrect because keeping the client NPO and holding medications, administering medications but holding anticonvulsants, and giving additional fluids and caffeine are not appropriate actions before an EEG.

Correct Answer: A

Rationale: The most critical time for assessment in a newborn is during the second period of reactivity, which occurs approximately 3-5 hours after delivery. During this phase, newborns are more likely to gag on mucus and aspirate, making it crucial for the nurse to assess their respiratory status first. Choice A indicates a newborn in this critical phase, requiring immediate assessment for potential airway compromise or respiratory distress. Choices B, C, and D do not present an immediate need for assessment related to airway compromise or respiratory distress.

Correct Answer: A

Rationale: The correct answer is walking in the hallway outside the operating room without a hair covering. In healthcare settings, it is crucial to adhere to infection control measures, which include wearing appropriate attire to prevent the spread of pathogens. Walking in the hallway outside the operating room without a hair covering violates these infection control protocols, necessitating immediate intervention by the charge nurse. Choices B and C are incorrect because putting on surgical attire before entering the operating room and wearing a surgical mask into the holding area are both standard practices that promote patient safety and infection control. Choice D is also incorrect as wearing scrubs from home into the nursing station, while not ideal, is not a violation that warrants immediate intervention compared to breaching infection control protocols near sensitive areas like the operating room.

Correct Answer: A

Rationale: When irrigating a wound, especially in the case of a full-thickness burn, it is crucial to use a solution that is gentle and non-irritating to the tissues. Sterile saline is the preferred choice for wound irrigation as it is isotonic and does not cause additional damage to the already compromised tissue. Distilled water lacks the electrolytes present in saline, Betadine scrub is not used for irrigation due to its potential to be cytotoxic, and tap water may introduce contaminants and microorganisms to the wound.
