The nurse is instructing a 65-year-old female client diagnosed with osteoporosis. The most important instruction regarding exercise would be to

A. Exercise by doing weight-bearing activities

B. Exercise to reduce weight

C. Avoid exercise activities that increase the risk of fracture

D. Exercise to strengthen muscles and thereby protect bones

Correct Answer: A
Rationale: The correct answer is A: Exercise by doing weight-bearing activities. Weight-bearing activities help strengthen bones and prevent further bone loss in clients with osteoporosis. This type of exercise includes activities like walking, dancing, and weightlifting, which help improve bone density. Choice B is incorrect because the primary focus should be on bone health, not weight reduction. Choice C is incorrect as avoiding all exercise activities that increase the risk of fracture can lead to muscle weakness and a decline in bone health. Choice D is also incorrect because while strengthening muscles is beneficial, the emphasis for osteoporosis management should be on weight-bearing exercises specifically.

A nurse is assisting with the development of strategies to prevent foodborne illnesses for a community group. The nurse should plan to include which of the following recommendations? (Select one that doesn't apply).

• A. Avoid unpasteurized dairy products.
• B. Keep cold food temperatures below 4.4°C (40°F).
• C. Discard leftovers after 48 hours.
• D. Wash raw vegetables thoroughly in clean water.

Correct Answer: C
Rationale: The correct answer is C. Discarding leftovers after 48 hours is not an effective recommendation to prevent foodborne illnesses. Leftovers should actually be discarded within 2 hours if they have been at room temperature. Choices A, B, and D are all effective strategies to prevent foodborne illnesses: avoiding unpasteurized dairy products reduces the risk of harmful bacteria, keeping cold food temperatures below 4.4°C (40°F) inhibits bacterial growth, and washing raw vegetables thoroughly removes contaminants.

The client is preparing for a myelogram. Which of the following statements by the client indicates a contraindication for this test?

• A. I can't lie in one position for more than thirty minutes.
• B. I am allergic to shrimp.
• C. I suffer from claustrophobia.
• D. I developed a severe headache after a spinal tap.

Correct Answer: B
Rationale: An allergy to shrimp is a contraindication for a myelogram because the contrast dye used in the procedure contains iodine, which can trigger allergic reactions in individuals allergic to shellfish. Choices A, C, and D are not contraindications for a myelogram. Inability to lie still for an extended period, claustrophobia, or a previous headache after a spinal tap are concerns that can be managed during the procedure but do not necessarily prevent the test from being performed.

A client is being maintained on heparin therapy for deep vein thrombosis. The nurse must closely monitor which of the following laboratory values?

• A. Bleeding time
• B. Platelet count
• C. Activated PTT
• D. Clotting time

Correct Answer: C
Rationale: Activated PTT is the correct lab value to monitor for clients on heparin therapy. Activated PTT (partial thromboplastin time) helps assess the effectiveness of heparin therapy by measuring the time it takes for blood to clot. Monitoring activated PTT ensures that the client is within the therapeutic range of heparin to prevent both clotting and bleeding complications. Bleeding time (Choice A) and platelet count (Choice B) are not specific indicators of heparin therapy effectiveness. Clotting time (Choice D) is not as sensitive as activated PTT in monitoring heparin therapy.

The client is receiving discharge teaching for heart failure. Which statement made by the client indicates a need for further teaching?

• A. I will weigh myself daily and report any significant weight gain to my healthcare provider.
• B. I will limit my sodium intake to help manage my heart failure.
• C. I will take my medications as prescribed by my healthcare provider.
• D. I will stop taking my medications if I feel better.

Correct Answer: D
Rationale: Choice D is the correct answer because stopping medications when feeling better can be harmful in heart failure. It is essential to complete the full course of medication as prescribed by the healthcare provider to effectively manage heart failure. Choices A, B, and C demonstrate good understanding and compliance with heart failure management strategies, such as monitoring weight, restricting sodium intake, and adhering to prescribed medications, respectively.
