Correct Answer: A

Rationale: The correct answer is A: Decreased resistance to infection. Lymphocytes are a crucial part of the immune system, responsible for fighting off infections. A decrease in the number of lymphocytes with age leads to a weakened immune response, making individuals more susceptible to infections. - Choice B: Cognitive problems, is not directly related to lymphocyte levels. - Choice C: Urinary incontinence, is not a typical effect of decreased lymphocytes. - Choice D: Decrease in various blood components, is too broad and not specific to the role of lymphocytes in immunity.

Correct Answer: A

Rationale: The correct answer is A because it addresses the specific nursing interventions needed for a patient with head injuries like J.E. Skin care and repositioning every 2 hours help prevent pressure ulcers. Maintaining extremity alignment prevents contractures. Respiratory exercises aid in lung expansion and prevent complications. The other choices are incorrect because they either lack essential interventions (B) or include unnecessary or inappropriate interventions (C, D). Teaching the use of an overhead trapeze is not necessary for head injuries, and intermittent positive pressure breathing therapy may not be indicated. Choice A provides a comprehensive and targeted approach to address the specific needs of a patient with head injuries.

Correct Answer: C

Rationale: The correct answer is C: An inference. When the nurse documents that the client is confused, it is an interpretation or conclusion drawn from the observed behavior or symptoms. Inferences are based on subjective and objective data. Subjective data (choice A) is based on what the client states, while a data cue (choice B) is a piece of information that may lead to an inference but is not the actual interpretation. Primary data (choice D) refers to firsthand information obtained directly from the client, which is not the case here. In this scenario, the nurse is making an inference based on the observed confusion, making choice C the correct answer.

Correct Answer: D

Rationale: The correct answer is D: A bleeding disorder. Thoracentesis involves inserting a needle into the pleural space to remove fluid. A bleeding disorder increases the risk of excessive bleeding during the procedure. This can lead to complications such as hematoma formation, pneumothorax, or even life-threatening bleeding. It is crucial to assess and address bleeding disorders before performing thoracentesis to ensure the safety of the client. A: A seizure disorder is not a contraindication for thoracentesis unless uncontrolled seizures could compromise the safety of the procedure. B: Anemia alone is not a contraindication for thoracentesis, as it does not directly increase the risk of complications during the procedure. C: Chronic obstructive pulmonary disease is not a contraindication for thoracentesis unless it is severe and compromises the client's ability to tolerate the procedure.

Correct Answer: C

Rationale: The correct answer is C: Psychomotor. The nurse is demonstrating psychomotor skills by inserting an IV catheter correctly. Psychomotor skills involve the ability to perform physical tasks effectively and efficiently. This skill requires coordination, dexterity, and precision. The other choices are incorrect because: A: Cognitive skills involve thinking, analyzing, and problem-solving. B: Interpersonal skills involve communication and interaction with others. D: Judgmental skills involve critical thinking and decision-making.
