Nursing Elites

1. A client has been receiving cyanocobalamin (B12) injections for the past 6 weeks. Which laboratory finding indicates that the medication is having the desired effect?

• A. Neutrophil count of 60%
• B. Basophil count of 0.5%
• C. Monocyte count of 2%
• D. Reticulocyte count of 1%

Correct answer: D

Rationale: Cyanocobalamin is a B12 medication used for pernicious anemia. A reticulocyte count of 1% indicates the desired effect of the medication, as reticulocytes are immature red blood cells that increase in response to B12 therapy, improving anemia. Neutrophils, basophils, and monocytes are white blood cells and are not directly influenced by B12 injections, making them incorrect choices.

2. The client is scheduled for surgical repair of a detached retina. What is the most likely preoperative nursing diagnosis for this client?

• A. Anxiety related to loss of vision and potential failure to regain vision.
• B. Deficient knowledge (preoperative and postoperative activities) related to lack of information.
• C. Acute pain related to tissue injury and decreased circulation to the eye.
• D. Risk for infection related to the eye injury.

Correct answer: A

Rationale: The correct preoperative nursing diagnosis for a client scheduled for surgical repair of a detached retina is 'Anxiety related to loss of vision and potential failure to regain vision.' A client facing the threat of permanent blindness due to a detached retina is likely to experience anxiety. Addressing this anxiety is crucial before providing education, as severe anxiety can hinder the client's ability to absorb new information. The nurse should offer emotional support, encourage the client to express concerns, and clarify any misconceptions. Acute pain is not a typical symptom of a detached retina, and the risk of infection preoperatively is minimal, making choices C and D less relevant in this scenario.

3. Nurses should understand the chain of infection because it refers to:

• A. the linkages involved in disease transmission.
• B. the sequence required for transmission of disease.
• C. the clustering of bacteria in a specific pattern.
• D. increasing virulence patterns among microorganisms.

Correct answer: B

Rationale: The chain of infection refers to the sequence required for the transmission of disease, involving steps like the pathogen's presence, movement from a reservoir, and entry into a susceptible host. Understanding this sequence helps healthcare professionals, including nurses, in implementing effective infection control measures. Choices A, C, and D are incorrect because they do not accurately describe the concept of the chain of infection. Choice A is too broad and does not specifically address the sequential nature of disease transmission. Choice C focuses on bacterial clustering rather than the transmission process. Choice D mentions virulence patterns, which are not the primary focus of the chain of infection concept.

4. A nurse at an outpatient clinic is returning phone calls that have been made to the clinic. Which of the following calls should have the highest priority for medical intervention?

• A. A home health patient reports, "I am starting to have a breakdown of my heels."?
• B. A patient that received an upper extremity cast yesterday reports, "I can't feel my fingers in my right hand today."?
• C. A young female reports, 'I think I sprained my ankle about 2 weeks ago.'
• D. A middle-aged patient reports, 'My knee is still hurting from the TKR.'

Correct answer: B

Rationale: The correct answer is the patient who received an upper extremity cast yesterday and reports not being able to feel their fingers in the right hand. This situation indicates a potential neurovascular issue that requires immediate attention to prevent complications. The other options are of lesser priority: A - Breakdown of the heels, while concerning, is not an acute issue that necessitates immediate intervention. C - An ankle sprain that occurred two weeks ago is now subacute and unlikely to be an urgent medical concern. D - Pain in the knee following a total knee replacement (TKR) is common in the early postoperative period and is not unexpected.

5. The nurse is caring for a 44-year-old client diagnosed with hypoparathyroidism. Which electrolyte imbalance is closely associated with hypoparathyroidism?

• A. Hypocalcemia.
• B. Hyponatremia.
• C. Hyperkalemia.
• D. Hypophosphatemia.

Correct answer: A.

Rationale: The correct answer is Hypocalcemia. In hypoparathyroidism, where the parathyroid glands are not producing sufficient parathyroid hormone, calcium levels become inadequate. This leads to hypocalcemia, characterized by symptoms such as muscle spasms, anxiety, seizures, hypotension, and congestive heart failure. Hyponatremia and hyperkalemia are not typically associated with hypoparathyroidism. While hyperphosphatemia can be seen in hypoparathyroidism due to decreasing calcium levels, the question specifically asks about the primary electrolyte imbalance closely related to hypoparathyroidism, which is hypocalcemia.
