A client with chronic kidney disease (CKD) and a bacterial infection receives a prescription for ciprofloxacin. The standard dose is 500 mg PO twice daily, but due to the patient's renal impairment, a dose adjustment of 50% is recommended. The medication is available in 250 mg tablets. How many tablets should the nurse administer? (Enter numerical value only.)

Rationale:
A. Meningitis B: This vaccine is not routinely indicated during or after pregnancy unless there is a specific risk factor or outbreak. It is not a standard postpartum immunization.

B. Measles, mumps, rubella: The MMR vaccine is live and contraindicated during pregnancy due to potential fetal harm. It should be given postpartum if the client is non-immune to prevent future infection.

C. Diphtheria, pertussis, tetanus: The Tdap vaccine is safe and recommended during each pregnancy, ideally between 27 and 36 weeks gestation, to provide passive immunity to the newborn.

D. Influenza vaccine: Inactivated influenza vaccine is recommended during pregnancy to protect both mother and baby. It should not be delayed until after pregnancy.

Rationale for Correct Choices

• 4 to 8 weeks: Sertraline, an SSRI, typically requires 4 to 8 weeks to reach its full therapeutic effect. This time frame allows for sufficient serotonin modulation, necessary for symptom improvement in conditions like PTSD and depression.
• Eye movement desensitization: Eye Movement Desensitization and Reprocessing (EMDR) is specifically recommended for PTSD. It involves guided eye movements that help the brain reprocess traumatic events and reduce emotional disturbance.
• Deep breathing: Deep breathing promotes parasympathetic nervous system activation, helping reduce anxiety and hyperarousal. It is a simple, accessible coping strategy to complement therapy and medication.

Rationale for Incorrect Choices

• 1 to 2 days: This timeframe is too short for an SSRI to have significant therapeutic effects. Any changes in mood or anxiety within this period are typically not due to the medication’s primary mechanism of action.
• 10 to 14 days: Although some mild improvement may begin, full therapeutic benefits of sertraline are not typically seen within this period. Clients are advised to continue consistent use for several weeks.
• Cognitive behavioural therapy: CBT is effective for many mental health disorders, including PTSD, but it does not involve the “reprocessing” component referenced.
• Prolonged exposure therapy: Prolonged exposure is used for PTSD treatment but focuses on gradually confronting trauma-related memories. It lacks the reprocessing element emphasized in the question.
• Progressive muscle relaxation: While useful for anxiety reduction, it is more complex and less immediate than deep breathing. It also requires a quiet space and more time, which may limit spontaneous use.
• Guided imagery: Guided imagery can reduce anxiety but involves visualization, which may not be suitable for individuals with intrusive trauma-related images. Deep breathing is simpler and more universally applicable.
