Nursing Elites

1. A child with a fever of 39°C (102.2°F) and a sore throat is brought to the clinic. The practical nurse suspects the child has streptococcal pharyngitis. Which diagnostic test should the practical nurse prepare the child for?

• A. Rapid antigen detection test.
• B. Throat culture.
• C. Complete blood count (CBC).
• D. Chest X-ray.

Correct answer: A

Rationale: A rapid antigen detection test is the appropriate diagnostic test for suspected streptococcal pharyngitis. This test is commonly used due to its quick results, helping in the prompt diagnosis and appropriate treatment of the condition. It specifically detects the presence of streptococcal antigens in the throat, aiding in confirming the diagnosis and guiding the healthcare provider in determining the most suitable treatment plan. Throat culture (Choice B) is a confirmatory test but is not as rapid as the rapid antigen detection test. Complete blood count (Choice C) and Chest X-ray (Choice D) are not specific tests for streptococcal pharyngitis and would not aid in confirming the diagnosis.

2. A parent of a 2-month-old infant, who was treated for pyloric stenosis, is receiving discharge instructions from a healthcare provider. Which statement by the parent indicates a need for further teaching?

• A. We will burp our baby more frequently during feedings
• B. We should feed our baby in an upright position
• C. We will lay our baby on their stomach after feeding
• D. We will start feeding our baby with small, frequent feedings

Correct answer: C

Rationale: Placing infants on their stomach after feeding increases the risk of sudden infant death syndrome (SIDS). It is important to educate parents to always place infants on their back to sleep to reduce this risk.

3. What information should be reinforced with the mother of a child with ringworm (Tinea)?

• A. Ringworm is not contagious.
• B. Tinea infections are indicative of poor hygiene and uncleanliness.
• C. Tinea infections are spread by direct and indirect contact.
• D. Ringworm often subsides spontaneously.

Correct answer: C

Rationale: The correct answer is C. Ringworm, a fungal infection, is highly contagious and can be spread by direct contact with infected individuals or animals and indirectly through contaminated objects. It is important for the mother to understand the modes of transmission to prevent the spread of the infection to others and to take necessary precautions to ensure proper treatment and containment of the condition. Choices A and D are incorrect because ringworm is indeed contagious, and it may not always subside spontaneously. Choice B is misleading as tinea infections are not solely indicative of poor hygiene; they can affect anyone, regardless of personal cleanliness.

4. The nurse provides information about the human papillomavirus (HPV) vaccine to the mother of a 14-year-old adolescent who came to the clinic this morning complaining of menstrual cramping. Which explanation should the nurse provide to support administering the HPV vaccine to the adolescent at this visit?

• A. Use of protective barriers during sexual activity prevents most strains of HPV infection
• B. Most adolescents are not honest about being sexually active
• C. Not all strains of HPV will be covered if given at a later date
• D. Immunity must be established to prevent future HPV infection and the risk for cervical cancer

Correct answer: D

Rationale: Administering the HPV vaccine helps establish immunity before potential exposure to the virus, reducing the risk of HPV infection and subsequent development of cervical cancer. It is recommended to vaccinate adolescents before they become sexually active for maximum effectiveness. Choice A is incorrect because while protective barriers can reduce the risk, they do not prevent all strains of HPV. Choice B is incorrect and judgmental as it assumes dishonesty without providing relevant information about HPV vaccination. Choice C is incorrect as it downplays the importance of vaccination by suggesting that not all strains are necessary to cover, which is not the case in preventing HPV-related diseases.

5. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?

• A. Metabolic alkalosis.
• B. Respiratory acidosis.
• C. Metabolic acidosis.
• D. Respiratory alkalosis.

Correct answer: A

Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.
