Question 1 of 5
What happens if folic acid is administered to treat anemia without determining its underlying cause?
Correct Answer: C
Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.
Question 2 of 5
A client asks a nurse working in a dental office what type of drug the dentist uses to provide anesthesia during the extraction of the client's wisdom teeth. The dentist uses an anesthetic gas, also known as laughing gas. This agent is:
Correct Answer: A
Rationale: The correct answer is nitrous oxide. Nitrous oxide is commonly known as laughing gas and is used as an anesthetic gas for procedures like dental extractions. It produces analgesia and mild euphoria without loss of consciousness. Nitrogen is a nonmetallic element found in air, while nitric oxide is a vasodilator produced from L-arginine. Nitrogen dioxide is a poisonous gas found in smog and exhaust fumes and is not used for anesthesia.
Question 3 of 5
During a petit mal seizure in the clinic, what should be the highest priority?
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.
Question 4 of 5
A patient's nurse taking a history notes complaints of SOB and weakness in the lower extremities. The patient has a history of hyperlipidemia and hypertension. Which of the following may be occurring?
Correct Answer: B
Rationale: In this scenario, the patient's symptoms of shortness of breath (SO
B) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness.
Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COP
D), or peripheral vascular disease (PV
D).
Question 5 of 5
Which sexually transmitted disease, sometimes referred to as the silent STD, is more common than gonorrhea and a leading cause of PID?
Correct Answer: D
Rationale: The correct answer is Chlamydia. Chlamydia is a common sexually transmitted infection that can often be asymptomatic, earning it the nickname 'silent STD.' It is more common than gonorrhea and is a leading cause of Pelvic Inflammatory Disease (PI
D). Genital herpes (
Choice
A) is a viral infection, not a bacterial STD like chlamydia. Trichomoniasis (
Choice
B) is a parasitic infection and not commonly associated with causing PID. Syphilis (
Choice
C) is a bacterial infection but is not as common as chlamydia and is not a leading cause of PID.
