Question 1 of 5
The physician orders local application of epinephrine 1:1000 solution to treat a nosebleed. The patient asks how this will help. Which of the ff. responses by the nurse is best?
Correct Answer: D
Rationale: The correct answer is D. Epinephrine, when applied locally, constricts blood vessels, reducing blood flow and slowing down bleeding. This vasoconstrictive effect helps control nosebleeds effectively. Choice A is incorrect because although epinephrine can raise blood pressure, it is not the primary mechanism for treating nosebleeds. Choice B is incorrect as epinephrine's bronchodilation effect is not relevant in this context. Choice C is incorrect as while promoting blood clotting is beneficial, epinephrine primarily acts by vasoconstriction to control bleeding.
Question 2 of 5
A baby is born temporarily immune to the diseases to which the mother is immune. The nurse understands that this is an example of which of the following types of immunity?
Correct Answer: A
Rationale: The correct answer is A: Naturally acquired passive immunity. This type of immunity occurs when antibodies are passed from mother to baby through the placenta or breast milk, providing temporary protection. The baby does not produce its antibodies, hence it is passive. Choice B, naturally acquired active immunity, involves the body producing its antibodies after exposure to a pathogen. Choice C, artificially acquired passive immunity, involves receiving preformed antibodies from an external source. Choice D, artificially acquired active immunity, involves the body producing antibodies in response to vaccination.
Question 3 of 5
A patient who was walking in the woods disturbed a beehive, was stung, and was taken to the emergency department immediately due to allergies to bee stings. Which of the ff. symptoms would the nurse expect to see upon admission of this patient? i.Pallor around the sting bites iv. Retinal hemorrhage ii.Numbness and tingling in the extremities v. Tachycardia iii.Respiratory stridor vi. Dyspnea
Correct Answer: D
Rationale: The correct answer is D: 4, 5, 2006. Upon admission, a patient with allergies to bee stings may exhibit tachycardia (increased heart rate) due to an allergic reaction. Respiratory stridor (high-pitched wheezing) may occur as a sign of airway inflammation. Retinal hemorrhage and dyspnea (difficulty breathing) are not typically associated with bee sting allergies. Pallor and numbness/tingling are also not common symptoms in this scenario. Therefore, choices A, B, and C are incorrect.
Question 4 of 5
Which of the following would the nurse evaluate as laboratory data that support the occurrence of AIDS?
Correct Answer: D
Rationale: The correct answer is D: 200 CD4+ cells. In AIDS, the immune system is severely compromised, leading to a decrease in CD4+ T cells. A CD4+ count below 200 cells/mm3 is a key indicator of AIDS, as it signifies advanced immunodeficiency. Choices A, B, and C all have CD4+ cell counts above 200, which would not support the occurrence of AIDS. Therefore, the nurse would evaluate a CD4+ count of 200 cells as laboratory data that support the occurrence of AIDS.
Question 5 of 5
The nurse is caring for a client with thrombocytopenia. What is the best way to protect this client?
Correct Answer: C
Rationale: The correct answer is C: Use the smallest needle possible for injections. This is important for a client with thrombocytopenia because they have a low platelet count, leading to an increased risk of bleeding. Using a small needle minimizes the risk of causing bleeding or bruising during injections. Limiting family visits (choice A) is not directly related to protecting the client from bleeding. Encouraging wheelchair use (choice B) is not specifically relevant to protecting the client with thrombocytopenia. Maintaining accurate fluid intake and output records (choice D) is important but not directly related to preventing bleeding in a client with thrombocytopenia.
