A mother states that she brought her child to the clinic because the 3-year-old girl was not keeping up with her siblings. During physical assessment, the nurse notes that the child has pale skin and conjunctiva and has muscle weakness. The hemoglobin on admission is 6.4 g/dl. After notifying the practitioner of the results, the nurse’s priority intervention is to:

Correct Answer: C

Rationale: The correct answer is C: Minimize energy expenditure to decrease cardiac workload. The child's low hemoglobin level of 6.4 g/dl indicates severe anemia, leading to reduced oxygen-carrying capacity. With pale skin, conjunctiva, and muscle weakness, the child likely has symptoms of anemia, causing fatigue and decreased exercise tolerance. By minimizing energy expenditure, the nurse can prevent further strain on the child's already compromised cardiovascular system, reducing the risk of cardiac complications. This intervention prioritizes the child's safety and well-being by addressing the immediate physiological concern of decreased oxygen supply to tissues. Summary of why the other choices are incorrect: A: Reducing environmental stimulation is not the priority as the child's main issue is related to severe anemia, not seizures. B: Repeating the analysis with a new specimen may be necessary to confirm the hemoglobin level but is not the immediate priority when dealing with a critically low hemoglobin level. D: Administering intr

Correct Answer: D

Rationale: The correct answer is D because T cells enter the lymph node via the bloodstream through high endothelial venules and exit via efferent lymphatics. This process allows them to circulate between lymph nodes and peripheral tissues to survey for pathogens. Option A is incorrect because efferent lymphatics carry lymph away from the lymph node. Option B is incorrect as T cells enter via the bloodstream, not afferent lymphatics. Option C is incorrect as T cells exit via efferent lymphatics, not afferent lymphatics.

Correct Answer: A

Rationale: The correct answer is A because a client with blood type B can receive blood type B and O. This is based on the compatibility rules for blood transfusions where individuals with blood type B can safely receive blood from donors with blood type B (as there are no antibodies against type B blood present in their system) and from universal donors with blood type O (since type O blood does not contain A or B antigens). Choice B is incorrect because individuals with blood type B should not receive blood type A due to the presence of A antigens. Choice C is incorrect because individuals with blood type B should not receive blood type AB as it contains both A and B antigens. Choice D is incorrect for the same reason as choice C.

Correct Answer: B

Rationale: The correct answer is B because feeling lightheaded and experiencing a drop in blood pressure upon standing are common clinical manifestations of anemia from acute blood loss. This indicates that the body is not able to adequately supply oxygen to tissues due to decreased red blood cell count. Option A is incorrect as focusing solely on high iron diet overlooks the immediate need for medical intervention. Options C and D are incomplete, thus cannot be evaluated.

Correct Answer: A

Rationale: The correct answer is A: Dyspnea with hiccups. Pericarditis is inflammation of the pericardium, leading to chest pain worsened by lying flat and relieved by sitting upright. Dyspnea (shortness of breath) may occur due to compression of the heart by fluid or inflammation. Hiccups can result from irritation of the diaphragm. Fever with chills (choice C) is more indicative of an infectious process. Tachycardia alone (choice D) is a nonspecific symptom and can occur in various conditions, but pericarditis typically presents with a combination of symptoms including chest pain and dyspnea.
