Nursing Elites

1. In a pediatric clinic, a nurse is assessing a child recently diagnosed with cystic fibrosis. Which of the following later findings of this disease would the nurse not expect to see at this time?

• A. Positive sweat test
• B. Bulky greasy stools
• C. Moist, productive cough
• D. Meconium ileus

Correct answer: C

Rationale: In a child newly diagnosed with cystic fibrosis (CF), noisy respirations and a dry, non-productive cough are typically the first respiratory signs to appear. The other options, including a positive sweat test, bulky greasy stools, and meconium ileus, are among the earliest findings of CF. CF is a genetic condition that affects the production of mucus, sweat, saliva, and digestive juices. Due to a defective gene, these secretions become thick and sticky instead of thin and slippery, leading to blockages in various passageways, especially in the pancreas and lungs. Respiratory failure is a severe consequence of CF, making it crucial to monitor respiratory symptoms closely in affected individuals. Therefore, a moist, productive cough would not be an expected finding in a newly diagnosed child with CF.

2. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?

• A. Heparin will dissolve clots that you have.
• B. Heparin will reduce the platelets that make your blood clot.
• C. Heparin will work better than warfarin.
• D. Heparin will prevent new clots from developing.

Correct answer: D

Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.

3. A nurse is caring for a patient with peripheral vascular disease (PVD). The patient complains of burning and tingling of the hands and feet and cannot tolerate touch of any kind. Which of the following is the most likely explanation for these symptoms?

• A. Inadequate tissue perfusion leading to nerve damage.
• B. Fluid overload leading to compression of nerve tissue.
• C. Sensation distortion due to psychiatric disturbance.
• D. Inflammation of the skin on the hands and feet.

Correct answer: A

Rationale: Patients with the peripheral vascular disease often sustain nerve damage as a result of inadequate tissue perfusion. Ischemic rest pain is more worrisome; it refers to pain in the extremity that is due to a combination of PVD and inadequate perfusion. Ischemic rest pain often is exacerbated by poor cardiac output. The condition is often partially or fully relieved by placing the extremity in a dependent position, so that perfusion is enhanced by the effects of gravity.

4. Which of the following medications taken by the patient is least likely to cause urine discoloration?

• A. Sulfasalazine
• B. Levodopa
• C. Phenolphthalein
• D. Aspirin

Correct answer: D

Rationale: The correct answer is Aspirin. Aspirin is not known to cause urine discoloration. Sulfasalazine is associated with causing orange-yellow discoloration of urine. Levodopa can cause darkening of urine to a brown or black color. Phenolphthalein has been linked to pink or red discoloration of urine. Therefore, among the options provided, Aspirin is the medication least likely to cause urine discoloration.

5. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

• A. Diarrhea and Vomiting
• B. Dizziness and Drowsiness
• C. Metallic taste
• D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.
