1. Chemicals, agents, or factors that cause physical defects in the developing embryo and are most harmful during organogenesis are:
- A. Teratogens
- B. Heterozygous
- C. Inborn errors
- D. Multifactorial
Correct answer: A
Rationale: Teratogens are substances that can cause congenital abnormalities, especially during the first trimester when organogenesis occurs. Choice A, Teratogens, is the correct answer as it specifically refers to substances that cause physical defects in the developing embryo. Choices B, Heterozygous, C, Inborn errors, and D, Multifactorial, are incorrect as they do not directly relate to substances that cause physical defects in embryos during organogenesis.
2. A 40-year-old man has been living with HIV for several years but experienced a significant decrease in his CD4+ levels a few months ago. The patient has just been diagnosed with Mycobacterium avium complex disease. The nurse should anticipate administering which of the following medications?
- A. Clarithromycin
- B. Pyrazinamide
- C. Rifapentine (Priftin)
- D. Azithromycin
Correct answer: A
Rationale: The correct answer is A: Clarithromycin. In the case of Mycobacterium avium complex disease, a common treatment regimen includes a macrolide antibiotic like clarithromycin or azithromycin in combination with other antimicrobials. Clarithromycin is a key component of the treatment due to its effectiveness against Mycobacterium avium complex. Choice B (Pyrazinamide) is not typically part of the standard treatment for this condition. Choice C (Rifapentine) is mainly used in tuberculosis treatment and is not a primary agent for Mycobacterium avium complex disease. Choice D (Azithromycin) is another suitable macrolide antibiotic for treating Mycobacterium avium complex disease but is not the medication typically used first-line.
3. What is the earliest age at which a satisfactory radial pulse can be taken in children?
- A. 1 year
- B. 2 years
- C. 3 years
- D. 6 years
Correct answer: C
Rationale: A satisfactory radial pulse can typically be taken starting at around 3 years of age, as younger children often have pulses that are too fast and irregular for accurate measurement.
4. A child with acetylsalicylic acid (aspirin) poisoning is being admitted to the emergency department. What early clinical manifestation does the nurse expect to assess on this child?
- A. Hematemesis
- B. Hematochezia
- C. Hyperglycemia
- D. Hyperventilation
Correct answer: D
Rationale: Early signs of aspirin poisoning include hyperventilation due to the stimulation of the respiratory center and the resultant respiratory alkalosis. Hematemesis, hematochezia, and hyperglycemia can occur later in the poisoning process or may not be directly related to aspirin toxicity.
5. A healthcare provider is evaluating the effectiveness of medication therapy for a client diagnosed with bipolar disorder. Which outcome should indicate that the medication has been effective?
- A. The client reports a decrease in manic episodes.
- B. The client experiences fewer mood swings.
- C. The client sleeps for 8 hours each night.
- D. The client maintains a stable weight.
Correct answer: A
Rationale: A decrease in manic episodes is a key indicator of the effectiveness of medication therapy for bipolar disorder. Manic episodes are a hallmark of bipolar disorder, and a decrease in their frequency or intensity suggests that the medication is helping to stabilize the client's mood and manage their symptoms. While choices B, C, and D are important aspects of overall health and well-being, they are not specific indicators of the effectiveness of medication therapy for bipolar disorder. Choice B focuses on mood swings in general, which may include depressive episodes as well, while choice C addresses sleep patterns and choice D relates to weight stability, which can be influenced by various factors unrelated to bipolar disorder treatment.
