Appropriate statements concerning intrathecal drug delivery systems include:

  • A. In a patient with progressive cancer-related pain, a low-grade pelvic infection is an absolute contraindication for implanting either an intrathecal catheter or a pump, even under antibiotic cover.
  • B. Intrathecally administered opioids circulate to the central neuraxis, including the brainstem, where they are likely to cause drowsiness and respiratory depression.
  • C. In difficult cases, ziconotide can be administered with either an opioid or clonidine, or both.
  • D. As a mixture of opioid and clonidine is expected to distribute throughout the cerebrospinal fluid, the level of the catheter in the intrathecal space is unlikely to be important.
Correct Answer: B

Rationale: Intrathecal drug delivery systems (IDDS) manage severe pain with nuances. A low-grade pelvic infection isn't an absolute contraindication; implantation may proceed with antibiotics if benefits outweigh risks (e.g., cancer palliation). Intrathecal opioids do reach the brainstem via cerebrospinal fluid, causing drowsiness and respiratory depression, though less than systemic routes due to lower doses still a key risk requiring monitoring. Ziconotide combines with opioids or clonidine for synergy in refractory pain, per clinical practice. Catheter tip position matters; drug distribution isn't uniform higher placement enhances rostral spread, affecting efficacy and side effects. MRI compatibility exists with most modern pumps. The brainstem effect of opioids underscores IDDS's potency and danger, necessitating careful titration and patient selection.

A 4 week old baby is due for her second Hepatitis B vaccine dose. However, you note that the baby is mildly jaundiced. What would be the most appropriate step to take next?

  • A. Screen for the Hepatitis B virus and only proceed with immunisation if the results are negative
  • B. Immunisation is not required as the baby may already have hepatitis
  • C. Give the hepatitis B vaccine and arrange for investigation for the jaundice
  • D. Proceed with the vaccination but also give the Hepatitis B immunoglobulin at another site
Correct Answer: C

Rationale: Mild jaundice at 4 weeks likely physiologic or breast milk, not hep B vaccine's safe, so jab and probe cause. Screening delays, skipping's wrong, deferring's cautious overkill, immunoglobulin's for exposure. Nurses roll this, a chronic vax-plus-check play.

The nurse teaches a patient who is scheduled for a prostate needle biopsy about the procedure. Which statement, if made by the patient, indicates that teaching was effective?

  • A. The biopsy will remove the cancer in my prostate gland.
  • B. The biopsy will determine how much longer I have to live.
  • C. The biopsy will help decide the treatment for my enlarged prostate.
  • D. The biopsy will indicate whether the cancer has spread to other organs.
Correct Answer: C

Rationale: Prostate biopsy snags tissue to check if enlargement's benign (BPH) or malignant guiding treatment like surgery or radiation. It's not therapeutic , doesn't predict lifespan , and staging spread needs more (e.g., scans). Nurses in oncology stress this it's a diagnostic linchpin, setting the course for managing prostate issues, critical for patient buy-in and clarity.

A 35-year old teacher on allopurinol 200 mg OM for the past year reports three recent gout attacks. BMI 27 kg/m2, BP 144/94 mm Hg. You notice tophi over both hands and elbows. You will now:

  • A. Stop the allopurinol during this acute gout attack
  • B. Start hydrochlorothiazide 25 mg OM for BP control
  • C. Continue allopurinol despite the attack and aim to reduce uric acid <300 umol/L
  • D. Advise to rest and avoid exercise for 3 months as he is having acute pain
Correct Answer: C

Rationale: Tophi, flares allopurinol stays, push uric <300; thiazides worsen, rest flops, losartan's late. Nurses hold this chronic crystal line.

Which does not require post exposure prophylaxis for rabies?

  • A. scratch
  • B. bite on face
  • C. bite on extremity
  • D. skin contact with blood, urine or faeces
Correct Answer: D

Rationale: Rabies PEP bites, scratches, bat splashes trigger; blood, pee, poop on skin don't. Nurses skip this chronic non-risk.

Obesity is now determined to be a disease because: i. Obesity is common. ii. The development of obesity results from established pathophysiology. iii. Obesity results in negative health consequences. iv. Obesity increases mortality.

  • A. i and ii
  • B. ii and iii
  • C. i and iv
  • D. ii, iii, and iv
Correct Answer: D

Rationale: Obesity's disease tag leans on pathophysiology hormone and brain glitches plus harm like diabetes and higher death rates, not just its spread. Commonness alone doesn't clinch it; mechanisms, outcomes, and mortality do. Clinicians bank on this trio, framing interventions, a chronic shift from mere prevalence to impact.
