What is the primary intervention for a patient with a pneumothorax?

Correct Answer: A

Rationale: The correct answer is to insert a chest tube. This intervention is considered the definitive treatment for a pneumothorax as it helps remove air or fluid from the pleural space, re-expanding the lung. Administering oxygen (Choice B) can be supportive but is not the primary intervention to treat a pneumothorax. Monitoring respiratory rate (Choice C) is important but does not address the underlying issue of air in the pleural space. Administering analgesics (Choice D) may help manage pain but does not treat the pneumothorax itself.

Correct Answer: A

Rationale: Infection and electrolyte imbalance are common complications of TPN. Infection can occur due to the invasive nature of TPN, which provides a direct route for pathogens. Electrolyte imbalances can arise from the composition of the TPN solution or improper monitoring. Hyperglycemia and sepsis (Choice B) are potential complications but are not as directly associated with TPN as infection and electrolyte imbalance. Kidney failure and hypovolemia (Choice C) are less common complications of TPN. Fluid overload and liver damage (Choice D) are potential complications but are not as frequently observed as infection and electrolyte imbalance.

Correct Answer: B

Rationale: The correct answer is B: Maintain two points of support on the ground at all times. When using a cane for left-leg weakness, the client should hold the cane in the right hand and advance the cane and the weak leg simultaneously. This technique provides the necessary support and stability. Option A is incorrect because the cane should be used on the side opposite the weakness to provide support. Option C is incorrect as advancing the cane too far with each step may cause the client to lose balance. Option D is incorrect because advancing the cane and the strong leg simultaneously does not provide the needed support for the weakened leg.

Correct Answer: D

Rationale: The correct answer is D because rinsing the mouth is essential to prevent staining and irritation caused by ferrous sulfate elixir. Choices A, B, and C are incorrect. Taking ferrous sulfate elixir before meals (Choice A) is not necessary. Mixing it with water (Choice B) is not recommended as it may alter the medication's effectiveness. Taking the medication once a week (Choice C) is incorrect as ferrous sulfate is usually prescribed daily or as directed by a healthcare provider.

Correct Answer: A

Rationale: Correct Answer: When assessing a patient for dehydration, healthcare professionals should monitor skin turgor, as it indicates the degree of dehydration, and check urine output, as decreased urine output can be a sign of dehydration. Choices B, C, and D are incorrect because they do not directly assess for dehydration. Assessing for jugular venous distention (B) is more relevant for heart failure, auscultating lung sounds and monitoring for fever (C) are more relevant for respiratory infections, and monitoring for cyanosis and increased respiratory rate (D) are more indicative of respiratory distress rather than dehydration.

Correct Answer: B

Rationale: To administer 10 mg of metoclopramide, the nurse should administer 2 mL (10 mg / 5 mg per mL). Therefore, the correct answer is 2 mL. Choice A (1 mL) is incorrect because it would only deliver 5 mg of metoclopramide, which is half the required dose. Choice C (3 mL) and D (4 mL) are incorrect as they would provide more than the required dose of 10 mg.

Correct Answer: C

Rationale: Chlordiazepoxide is a benzodiazepine commonly used to manage anxiety and prevent seizures during alcohol withdrawal. Haloperidol (Choice A) is an antipsychotic medication and is not typically used for alcohol withdrawal. Disulfiram (Choice B) is used in the treatment of alcohol use disorder but is not indicated for alcohol withdrawal. Phenobarbital (Choice D) may be used for alcohol withdrawal seizures but is not the first-line medication for managing alcohol withdrawal symptoms.

Correct Answer: A

Rationale: The correct answer is to insert a chest tube. In managing a patient with a suspected pneumothorax, the priority is to relieve the pressure from the pneumothorax by inserting a chest tube. Monitoring respiratory status (choice B) is important but comes after ensuring proper management of the pneumothorax. Administering oxygen (choice C) can help support oxygenation but does not address the underlying issue of pressure in the thoracic cavity. Calling for assistance (choice D) can be done concurrently with managing the pneumothorax, but the immediate intervention to address the pneumothorax itself is chest tube insertion.

Correct Answer: B

Rationale: The correct answer is B: 'Walk for 1-2 hours each day.' After vein ligation and stripping, walking helps promote circulation and aids in the recovery process. Option A is incorrect as remaining sedentary for 2-3 days can lead to decreased circulation and potentially increase the risk of complications. Option C is incorrect because compression stockings should typically be worn during the day to support circulation. Option D is incorrect as elevating the legs while sitting is beneficial, but walking is more effective in promoting circulation and recovery in this case.
