Which antibiotic is not recommended as first line therapy for the associated bug?
- A. legionella - erythromycin
- B. chlamydia psittaci - doxycycline
- C. chlamydia pneumoniae - doxycycline
- D. mycoplasma pneumoniae - roxithromycin
Correct Answer: C
Rationale: Chlamydia pneumoniae doxycycline's gold, not erythromycin, roxi, or others mispaired. Nurses tweak this chronic lung fix.

Which of these does not need treatment of the sexual partner?
- A. trichomonas vaginalis
- B. bacterial vaginosis
- C. candida

Correct Answer: B
Rationale: BV vaginal flora shift, not partner-fed; trich, chlamydia, gonorrhea, candida swap. Nurses skip this chronic duo fix.
Your junior trainee has been in theatre for 5 h with a patient undergoing a femorodistal bypass procedure. He is yawning and seems withdrawn. The trainee's fatigue is likely to be improved by:
- A. Imbibing one 60 ml shot of espresso coffee.
- B. Taking a 1-h nap.
- C. Increasing the brightness of the theatre lighting.
- D. Walking around and chatting to other members of staff.
Correct Answer: B
Rationale: Fatigue during long procedures impairs performance. A 60 ml espresso shot (50-100 mg caffeine) boosts alertness temporarily (20-30 minutes onset), but its effect wanes after 5 hours of sustained effort. A 1-hour nap restores cognitive function and vigilance significantly, countering sleep pressure per sleep research (e.g., NASA nap studies), with benefits lasting hours. Bright lighting enhances alertness via circadian stimulation but is less effective mid-fatigue. Walking and chatting provide a break, mildly boosting arousal, but lack restorative depth. Microsleeps signal severe fatigue, worsening performance. A nap's superiority lies in addressing accumulated sleep debt, critical in high-stakes settings like surgery, offering sustained recovery over stimulants or environmental tweaks.
Which of the following is NOT an early warning symptom of hypoglycaemia?
- A. Tremors
- B. Palpitations
- C. Diaphoresis
- D. Giddiness, drowsiness
Correct Answer: D
Rationale: Hypo's early buzz tremors, palpitations, sweat, anxiety screams adrenaline, waking patients to act. Giddiness and drowsiness lag, hitting as brain sugar drops, a later neuroglycopenic fade, not the first alarm. Clinicians teach this split, pushing quick carbs at the front signs, a chronic drill to dodge the haze.
A client with cancer is admitted to a short-term rehabilitation facility. The nurse prepares to administer the client's oral chemotherapy medications. What action by the nurse is most appropriate?
- A. Crush the medications if the client cannot swallow them.
- B. Give one medication at a time with a full glass of water.
- C. No special precautions are needed for these medications.
- D. Wear personal protective equipment when handling the medications.
Correct Answer: D
Rationale: Oral chemotherapy drugs, like their IV counterparts, are hazardous due to their cytotoxic properties, posing risks to healthcare workers through skin contact or inhalation during handling. The most appropriate action is for the nurse to wear personal protective equipment (PPE), such as gloves, to minimize exposure, aligning with oncology safety standards. Crushing these medications is contraindicated, as it increases the risk of aerosolizing toxic particles, endangering both nurse and client many are labeled do not crush.' Giving one at a time with water isn't necessary unless specified and doesn't address safety. Assuming no precautions are needed ignores the drugs' hazardous nature, risking occupational exposure. Using PPE ensures safe administration, protects the nurse's health, and maintains the medication's integrity, reflecting best practices in cancer care where handling precautions are non-negotiable.
The movement patterns of 80 students who participated in a training programme have been measured. One of the measurement variables is the number of hours the student plays sports per week. This variable is measured both after and before the training programme. Subsequently, the average number of hours the student played sports before the training programme is compared with the number of hours the student plays sports after the training programme. Question: Which test is suitable to compare these two average values?
- A. Chi-square test
- B. Fisher's exact test
- C. Two-sample t-test
- D. Paired t-test
Correct Answer: D
Rationale: Same kids, before-after sports hours paired t-test ties each shift, not chi-square's counts, Fisher's tables, or two-sample splits. Nurses stat this, a chronic match check.
