What are the periods in life when the need for iron increases?
- A. Pregnancy
- B. Infancy
- C. Old age
- D. Male reproductive years
Correct Answer: A
Rationale: The need for iron increases during pregnancy primarily due to the increased blood volume to support the growing fetus and placenta. Iron is essential for the production of hemoglobin, which helps transport oxygen to both the mother and the developing baby. Pregnant women often require more iron to prevent iron deficiency anemia, which can have negative effects on both the mother and the baby. It is important for pregnant women to consume enough iron-rich foods or take iron supplements as recommended by their healthcare provider to support a healthy pregnancy.

Which strategies should the school nurse recommend implementing in the classroom for a child with attention deficit hyperactive disorder (ADHD)? (Select all that apply.)
- A. Schedule heavier subjects to be taught in the afternoon.
- B. Accompany verbal instructions by written format.
- C. Limit number of breaks taken during instructional periods.
- D. Allow more time for testing.
Correct Answer: B
Rationale: Accompany verbal instructions by written format: Children with ADHD may have difficulty retaining verbal instructions due to their distractibility and impulsivity. Providing written instructions alongside verbal ones can help reinforce the information and improve comprehension.
Which of the ff suggestions should a nurse give breastfeeding mothers to prevent or eliminate mastitis and breast abscess? Choose all that apply
- A. Offer the opposite breast at each feeding to their
- B. Avoid frequent nursing of the infants
- C. Avoid breastfeeding
- D. Ensure that their hands and breasts are clean
Correct Answer: D
Rationale: Keeping hands and breasts clean is crucial in preventing infections like mastitis and breast abscess. Proper hygiene practices can help reduce the risk of introducing harmful bacteria to the breast during breastfeeding. It is essential for breastfeeding mothers to wash their hands before each feeding session and ensure that the breast is clean before nursing.
Which type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?
- A. Neurogenic
- B. Cardiogenic
- C. Hypovolemic
- D. Anaphylactic
Correct Answer: D
Rationale: Anaphylactic shock is characterized by a severe, systemic hypersensitivity reaction that can occur in response to allergens such as certain drugs or latex. During anaphylactic shock, the body releases large amounts of histamine and other inflammatory substances, leading to widespread vasodilation (dilation of blood vessels) and increased capillary permeability. This results in a rapid drop in blood pressure, decreased perfusion to vital organs, and potential life-threatening symptoms such as difficulty breathing and cardiovascular collapse. Immediate treatment with epinephrine and supportive measures such as intravenous fluids is crucial in managing anaphylactic shock.
Barbiturate anticonvulsants are effective in treating all of these seizure types, except:
- A. partial seizures.
- B. febrile seizures.
- C. tonic-clonic seizures.
- D. absence seizures.
Correct Answer: D
Rationale: Barbiturate anticonvulsants are effective in treating partial seizures, tonic-clonic seizures, and febrile seizures. However, they are not considered first-line treatment for absence seizures. Absence seizures typically respond better to other anticonvulsant medications such as ethosuximide or valproic acid. Barbiturates have a sedative effect and can cause drowsiness or cognitive impairment, which may not be ideal for managing absence seizures where maintaining alertness and cognitive function is important.
Following a splenectomy, a client has a hemoglobin (Hb) level of 7.5g/dl and has vertigo when getting out of bed. The nurse suspects abnormal orthostatic changes. The vital sign values that would most support the nurse's analysis are:
- A. Rise in blood pressure and heart rate
- B. Rise in blood pressure and drop in heart rate
- C. Drop in blood pressure and rise in heart rate
- D. none of the above
Correct Answer: C
Rationale: Following a splenectomy, the client's hemoglobin level of 7.5g/dl indicates anemia, which can contribute to orthostatic hypotension. When the client changes position from lying to standing, the decrease in blood volume may lead to a drop in blood pressure. Additionally, the compensatory mechanism to maintain perfusion to vital organs is to increase the heart rate. Therefore, the vital sign values that would most support the nurse's analysis are a drop in blood pressure (hypotension) and a rise in heart rate (tachycardia).
