NCLEX-PN Quizlet 2023 - Nurselytic

Correct Answer: A

Rationale: Given the client's symptoms of fatigue, shortness of breath, and lightheadedness, along with her gender and fad dieting, the most likely cause is iron deficiency. Iron deficiency commonly presents with these symptoms due to decreased oxygen-carrying capacity in the blood. Folate deficiency would typically present with different symptoms such as mouth sores and changes in skin, not fitting the client's presentation. Peptic ulcer would manifest with abdominal pain, not primarily with the symptoms described. Iron overload would present with symptoms such as joint pain and fatigue, which are not consistent with the client's presentation.

Correct Answer: C

Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding. Pernicious anemia results from vitamin B12 deficiency due to a lack of intrinsic factor, leading to faulty absorption from the gastrointestinal tract. While pernicious anemia can lead to other health issues, bleeding tendencies are not a primary concern. Metastatic liver cancer (choice
A) can cause liver dysfunction leading to decreased synthesis of clotting factors, increasing the risk of bleeding. Gram-negative septicemia (choice
B) can lead to disseminated intravascular coagulation (DI
C) causing excessive bleeding. Iron-deficiency anemia (choice
D) can result in microcytic hypochromic red blood cells, which can impair oxygen transport and lead to tissue hypoxia, but it is not directly associated with a significant potential for bleeding.

Correct Answer: C

Rationale: When administering intravenous electrolyte solutions, preventing the infiltration of calcium is crucial to avoid tissue necrosis and sloughing, making choice C the correct answer.
Choice A is revised to 'Infuse hypertonic solutions cautiously' because hypertonic solutions should be infused cautiously to prevent adverse effects.
Choice B is corrected to 'Mix no more than 60 mEq of potassium per liter of fluid' as exceeding this limit can lead to hyperkalemia.
Choice D is modified to 'Monitor the client's digitalis dosage for adjustments due to IV calcium' as it is essential to monitor the digitalis dosage for potential adjustments when IV calcium is administered; however, this choice is incorrect here as it inaccurately suggests adjusting the digitalis dosage due to IV calcium, which could lead to harmful effects.

Correct Answer: B

Rationale: Folic acid deficiency in the mother has been primarily associated with neural tube defects in the fetus. Folic acid is crucial for the development of the neural tube in the early stages of pregnancy. Its deficiency can lead to neural tube defects, such as spina bifida or anencephaly. Iron deficiency is not directly related to neural tube defects but can cause other complications in pregnancy. Vitamin B12 is important for neurological function but is not the primary cause of neural tube defects. Vitamin E deficiency is not associated with neural tube defects in the fetus.

Correct Answer: D

Rationale: Atropine is the medication most commonly recognized for the treatment of symptomatic bradycardia because it increases the rate of conduction in the AV node, helping to alleviate bradycardia. Questran is a medication used to lower cholesterol levels and is not indicated for bradycardia. Digitalis, such as Digoxin, is used for heart failure and atrial fibrillation but not typically for bradycardia. Nitroglycerin is primarily used for angina and not bradycardia.
