Correct Answer: A

Rationale: The correct answer is A because observing for signs of brain injury is crucial in assessing a possible skull fracture. Signs may include altered mental status, headache, nausea, vomiting, and unequal pupil size. Choice B is incorrect as hemorrhaging from the oral cavity may not always be present in skull fractures. Choice C is incorrect as elevating the foot of the bed is not recommended for a possible skull fracture. Choice D is incorrect as decreased intracranial pressure and temperature are not typical symptoms of a skull fracture.

Correct Answer: A

Rationale: The correct answer is A: Where is the pain located? In the PQRST mnemonic, "P" stands for provocation, "Q" for quality, "R" for region/radiation, "S" for severity, and "T" for timing. The question "Where is the pain located?" corresponds to the "R" component, which is region/radiation. This question helps the nurse identify the specific area where the pain is localized, which can provide valuable information for diagnosis. Explanation of other choices: B: What causes the pain? This question relates more to the "P" component, which is provocation, rather than the region/radiation aspect. C: Does it come and go? This question pertains to the "T" component, which is timing, focusing on the pattern of the pain rather than the specific location. D: What does the pain feel like? This question is more aligned with the "Q" component, which is quality,

Correct Answer: A

Rationale: Step-by-step rationale for the correct answer (A): 1. Increased RBC: Hemolytic anemia leads to increased RBC production as the body compensates for the destruction of red blood cells. 2. Decreased bilirubin: Bilirubin levels decrease due to the accelerated breakdown of red blood cells. 3. Decreased Hgb and Hct: Hemolysis causes a decrease in hemoglobin and hematocrit levels as red blood cells are destroyed. 4. Increased reticulocytes: Reticulocytes are immature red blood cells released by the bone marrow in response to increased RBC destruction. Summary: - Choice B is incorrect as hemolytic anemia would lead to increased, not decreased, bilirubin levels. - Choice C is incorrect as hemolytic anemia would lead to decreased, not increased, Hgb and Hct levels. - Choice D is incorrect as hemolytic anemia would not lead to increased levels of all parameters

Correct Answer: D

Rationale: The correct answer is D because pleural effusion is the accumulation of fluid in the pleural space. When auscultating the lungs of a client with pleural effusion, the examiner would note decreased or absent breath sounds over the area where the fluid has accumulated. This is due to the fluid blocking the transmission of sound through the lungs. Pronounced breath sounds (choice A) would not be present due to the fluid obstructing the normal sound transmission. Expiratory wheezes (choice B) are associated with airway obstruction, not fluid accumulation. Friction rub (choice C) is a dry, grating sound heard with inflammation of the pleura, not specifically related to pleural effusion.

Correct Answer: A

Rationale: The correct answer is A because completing a comprehensive database is part of the first phase of the nursing process, which is assessment. During assessment, the nurse gathers data about the patient's health status. This information is crucial for identifying health problems, developing nursing diagnoses, planning interventions, and evaluating outcomes. Choice B is incorrect because identifying nursing diagnoses is part of the second phase, which is diagnosis. Choice C is incorrect as intervening based on priorities of patient care is part of the third phase, which is planning. Choice D is incorrect because determining whether outcomes have been achieved is part of the fourth phase, which is evaluation.
