Is working as a nurse safe during pregnancy?

What does the evidence say about working as a nurse during pregnancy?

1. NIOSH says prolonged standing, heavy lifting, repeated bending, floor-level lifting, overhead reaching, and awkward lifting may increase reproductive or musculoskeletal risk. It suggests discussing task-specific limits and reducing or avoiding standing for three hours or more when possible. 1
2. NIOSH states that night work, rotating shifts, and long hours may increase miscarriage and preterm-birth risk and often reduce sleep. This is an association-based occupational concern, not proof that a particular shift caused an outcome. 2
3. CDC says pregnant healthcare personnel are not routinely excluded from caring for patients with infections solely because of pregnancy when recommended precautions protect staff. Occupational health should coordinate exposure assessment and obstetric referral, while novel or high-consequence pathogens may prompt specific restrictions. 3
4. NIOSH reports that healthcare workers who prepare, administer, or work near hazardous drugs can be exposed and that published workplace studies associate these exposures with infertility, spontaneous abortion, and congenital malformations. Risk depends on drug toxicity and exposure amount. 4
5. NIOSH says heavy waste-anesthetic-gas exposure may be associated with reduced fertility and increased miscarriage risk. Proper ventilation and scavenging reduce exposure; surgical and charcoal masks do not block anesthetic gases, and any respirator must be selected and fitted for the specific chemical. 5

Is working as a nurse safe in each trimester?

• First trimester. Tell occupational health early enough to review hazardous-drug duties, anesthetic-gas controls, vaccination and immunity records, respirator fit, and exposure procedures. Reproductive hazards may matter before pregnancy is visible, so do not wait for symptoms or a routine unit schedule change.
• Second trimester. Reassess patient transfers, floor lifts, repetitive bending, overhead reach, prolonged standing, breaks, hydration, and shift recovery as body mechanics change. Use lift equipment and team assistance rather than relying on a single universal weight cutoff that ignores lift height, frequency, posture, and individual factors.
• Third trimester. Balance and posture changes can increase fall and musculoskeletal risk. Review emergency-response roles, compression or rest options if advised, secure access to breaks, and a plan for contractions, bleeding, fluid leakage, dizziness, or other urgent symptoms during a shift.
