Nursing Elites

1. The PN is caring for a client with diabetes insipidus. The nurse can expect the lab work to show:

• A. elevated urine osmolarity and elevated serum osmolarity.
• B. decreased urine osmolarity and decreased serum osmolarity.
• C. elevated urine osmolarity and decreased serum osmolarity.
• D. decreased urine osmolarity and elevated serum osmolarity.

Correct answer: D

Rationale: In diabetes insipidus, the pituitary releases too much antidiuretic hormone (ADH), causing the client to produce a large amount of dilute urine (decreased osmolarity) and leading to dehydration (elevated serum osmolarity). Therefore, the correct answer is decreased urine osmolarity and elevated serum osmolarity. Choice C, elevated urine osmolarity and decreased serum osmolarity, is incorrect for diabetes insipidus, as it is more characteristic of syndrome of inappropriate ADH (SIADH). Choices A and B, elevated urine osmolarity and elevated serum osmolarity, and decreased urine osmolarity and decreased serum osmolarity, respectively, are generally not seen in diabetes insipidus, as urine and serum osmolarity typically move in opposite directions in this condition.

2. Why is it often necessary to draw a complete blood count and differential (CBC/differential) when a client is being treated with an antiepileptic drug (AED)?

• A. The hematocrit is adversely affected due to increased vascular volume.
• B. AEDs can lead to blood dyscrasia as a side effect.
• C. AEDs may cause aplastic anemia and megaloblastic anemia.
• D. Some AEDs induce white blood cell reduction.

Correct answer: B

Rationale: When a client is being treated with antiepileptic drugs (AEDs), it is essential to monitor for potential side effects on blood parameters. Some AEDs can lead to blood dyscrasia, which includes conditions like aplastic anemia and megaloblastic anemia. Therefore, drawing a complete blood count and differential helps in identifying these adverse effects early. Choices A, C, and D are incorrect because the primary concern when monitoring blood parameters in clients on AEDs is the risk of blood dyscrasia, not changes in hematocrit due to vascular volume, white blood cell reduction, or immune modulation.

3. One day postoperative, the client complains of dyspnea, and his respiratory rate (RR) is 35, slightly labored, and there are no breath sounds in the lower-right base. The nurse should suspect:

• A. cor pulmonale.
• B. atelectasis.
• C. pulmonary embolism.
• D. cardiac tamponade.

Correct answer: B

Rationale: The correct answer is atelectasis. The absence of breath sounds in the lower-right base is a key finding in atelectasis, which occurs when a portion of the lung collapses. The other symptoms such as dyspnea and increased respiratory rate could be present in various pulmonary conditions. Cor pulmonale is typically associated with chronic lung disease, pulmonary embolism presents with sudden onset dyspnea and chest pain, and cardiac tamponade manifests with Beck's triad of hypotension, distended neck veins, and muffled heart sounds.

4. Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?

• A. metastatic liver cancer
• B. gram-negative septicemia
• C. pernicious anemia
• D. iron-deficiency anemia

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 (DIC) 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.

5. During a petit mal seizure in the clinic, what should be the highest priority?

• A. Provide a safe environment free of obstructions in the immediate area
• B. Call a code
• C. Contact the patient's physician
• D. Prevent excessive movement of the extremities

Correct answer: A

Rationale: During a petit mal seizure, the highest priority is to provide a safe environment free of obstructions in the immediate area. This action aims to prevent injuries to the patient during the seizure. While calling a code or contacting the patient's physician may be necessary at some point, immediate safety measures take precedence. Preventing excessive movement of the extremities is relevant but ensuring a safe environment is crucial to avoid harm during the seizure.
