1. When caring for an asthmatic patient with an early-phase reaction, which of the following is indicative of an early-phase reaction?
- A. Rapid bronchospasms
- B. Inflammatory epithelial lesions
- C. Increased secretions
- D. Increased mucosal edema
Correct answer: A
Rationale: Rapid bronchospasms are a symptom of an early-phase reaction in an asthmatic patient. During the early phase, bronchospasms occur due to immediate hypersensitivity reactions. Inflammatory epithelial lesions, increased secretions, and increased mucosal edema are typically seen in late-phase reactions as part of the inflammatory response that occurs later. Therefore, rapid bronchospasms are most indicative of an early-phase reaction.
2. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?
- A. The patient is allergic to shellfish.
- B. The patient has a pacemaker.
- C. The patient suffers from claustrophobia.
- D. The patient takes antipsychotic medication.
Correct answer: B
Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.
3. Administration of hepatitis B vaccine to a healthy 18-year-old patient has been effective when a specimen of the patient's blood reveals
- A. HBsAg.
- B. anti-HBs
- C. anti-HBc IgG
- D. anti-HBc IgM.
Correct answer: B
Rationale: The correct answer is 'anti-HBs'. The presence of surface antibody to HBV (anti-HBs) indicates a successful response to the hepatitis B vaccine. Anti-HBs is a marker of immunity and protection against hepatitis B infection. Choices A, C, and D are incorrect because: A) HBsAg indicates current infection with hepatitis B virus, C) anti-HBc IgG suggests past infection or immunity, and D) anti-HBc IgM is a marker of acute hepatitis B infection.
4. The nurse is reviewing the lab results of a patient taking lithium for schizoaffective disorder. The lab results show that the blood lithium value is 1.7 mcg/L. What would the nurse take as the priority action?
- A. Induce vomiting
- B. Hold the next dose of Lithium
- C. Administer an antiemetic
- D. Give the next dose of Lithium
Correct answer: B
Rationale: The correct answer is to hold the next dose of Lithium. The blood lithium value of 1.7 mcg/L exceeds the therapeutic range of 0.5-1.5 mcg/L, indicating potential toxicity. Holding the next dose is crucial to prevent further accumulation of lithium in the bloodstream. Inducing vomiting is not appropriate in this situation as the priority is to prevent further absorption of lithium. Administering an antiemetic is not the priority in lithium toxicity. Giving the next dose of lithium would exacerbate the toxicity and should be avoided.
5. A client comes to the clinic for treatment of recurrent pelvic inflammatory disease. The nurse recognizes that this condition most frequently follows which type of infection?
- A. Trichomoniasis
- B. Chlamydia
- C. Staphylococcus
- D. Streptococcus
Correct answer: B
Rationale: Chlamydial infections are one of the most common causes of salpingitis or pelvic inflammatory disease. Chlamydia can ascend from the vagina or cervix to the reproductive organs, leading to inflammation and infection. Trichomoniasis, caused by a parasite, typically presents with different symptoms than pelvic inflammatory disease and is not the primary cause. Staphylococcus and Streptococcus are bacteria that can cause other types of infections but are not the primary culprits in most cases of pelvic inflammatory disease.
