Correct Answer: C

Rationale: The correct answer is C: Diarrhea. Ranitidine, which is used to treat peptic ulcer disease, can lead to gastrointestinal disturbances such as diarrhea. Choices A, B, and D are incorrect. Hypertension and hypotension are not common side effects of ranitidine. Constipation is also not a typical side effect associated with ranitidine use.

Correct Answer: B

Rationale: The correct answer is B because the statement "I'd rather not talk about it right now" indicates that the client is consciously choosing to avoid discussing the distressing issue, which aligns with the mechanism of suppression. Choice A does not involve active avoidance but rather memory loss, which is not suppression. Choice C involves blaming others, which is a defense mechanism known as projection. Choice D involves expressing emotions rather than avoiding them, which does not align with suppression.

Correct Answer: B

Rationale: The correct answer is B: Insertion of a chest tube. In a case of spontaneous pneumothorax, the primary intervention is to insert a chest tube. This procedure allows the trapped air to escape from the pleural space, relieving pressure and enabling the lung to re-expand. Choices A, C, and D are not the initial interventions for spontaneous pneumothorax. Cardiopulmonary resuscitation is indicated for cardiac arrest, oxygen therapy may provide supportive care but does not address the underlying issue of trapped air in the pleural space, and assisted ventilation may be needed later but is not the first-line treatment for a pneumothorax.

Correct Answer: A

Rationale: The correct method for administering a tuberculosis (TB) test is through an intradermal injection on the forearm. This technique allows for the proper administration of the test under the skin to assess the body's response to the TB antigen. Choices B, C, and D are incorrect because the TB test specifically requires an intradermal injection, not subcutaneous, intramuscular, or oral administration.

Correct Answer: A

Rationale: The correct answer is A: Alcohol use during pregnancy. The physical features mentioned are indicative of fetal alcohol syndrome, a condition caused by maternal alcohol consumption during pregnancy. It is crucial for the nurse to inquire about alcohol use as it can help in diagnosing and managing the infant's condition. Choices B, C, and D are incorrect as they are not directly associated with the physical findings described in the newborn, which specifically point towards a potential history of alcohol exposure during pregnancy.
