Correct Answer: B

Rationale: The correct manifestation to expect when collecting data from a client with PTSD is hypervigilance. Hypervigilance refers to increased alertness, which is a common symptom of PTSD. This heightened state of awareness is characterized by an exaggerated startle response, being easily startled, and constantly scanning the environment for potential threats. Amnesia (choice A) is not typically a primary manifestation of PTSD; it is more commonly associated with dissociative disorders. Hallucinations (choice C) involve perceiving things that are not present and are not typically a hallmark symptom of PTSD. Severe agitation (choice D) may occur in individuals with PTSD, but hypervigilance is a more specific and common manifestation associated with this disorder.

Correct Answer: A

Rationale: Corrected Rationale: Untreated fluid overload can lead to complications such as pulmonary edema and congestive heart failure. Pulmonary edema occurs when excess fluid accumulates in the lungs, leading to difficulty breathing and potentially life-threatening respiratory distress. Congestive heart failure can result from the heart's inability to pump effectively due to the excess fluid volume, leading to symptoms such as fatigue, shortness of breath, and fluid retention. Choices B, C, and D are incorrect because hypertension, liver failure, pulmonary embolism, and dehydration are not the primary complications directly associated with untreated fluid overload.

Correct Answer: C

Rationale: The correct answer is to monitor the client's fluid and electrolyte levels. When caring for a client with dehydration, it is crucial to assess and monitor their fluid and electrolyte status to guide appropriate interventions. Administering antiemetics may help with nausea but does not address the underlying issue of dehydration. Encouraging the client to drink oral rehydration solutions is beneficial but may not be the immediate priority if the client is severely dehydrated. Administering intravenous fluids may be necessary based on the assessment of fluid and electrolyte levels, making monitoring these levels the priority intervention.

Correct Answer: B

Rationale: The correct answer is B because avoiding perfumed lotions is important to prevent skin irritation after radiation therapy. Using a heating pad (A) can further damage the skin, applying cold compresses (C) may not be recommended, and scrubbing the area daily with soap and water (D) can be too harsh on the skin, leading to further irritation and damage.

Correct Answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
